We look at the division of 43244730 by 345 
We want to figure out the number of times 43244730 can be divided by 345.

Step 1:
345 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 345

On to step 2:
When dividing 43 by 345, we get 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Fetch the next digit (2) from the dividend, attach it to 43 and continue: 432 / 345

Going ahead to step 3:
345 can be fit into 432 1 times, resulting in a remainder of 87.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 345 from 432 leaves us with 87.
Append the next digit (4) from the dividend to 87 and continue with: 874 / 345

Let's proceed to step 4:
If we divide 874 by 345, we get 2 and a remainder of 184.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 690 away from 874, we end up with 184.
Fetch the next digit (4) from the dividend, attach it to 184 and continue: 1844 / 345

Advancing to step 5:
1844 divided by 345 is 5 with a remainder of 119.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
If we subtract 1725 from 1844, we get 119.
Append the next digit (7) from the dividend to 119 and continue with: 1197 / 345

Advancing to step 6:
When dividing 1197 by 345, we get 3 with a remainder of 162.
The next digit of our result is 3. 
Result so far: 1253.0
If we take 1035 away from 1197, we end up with 162.
Include the next digit (3) from the dividend after 162, then repeat: 1623 / 345

Let's proceed to step 7:
If we divide 1623 by 345, we get 4 and a remainder of 243.
Put 4 as the next digit of the answer. 
Result so far: 12534.0
Deduct 1380 from 1623 and we're left with 243.
Include the next digit (0) from the dividend after 243, then repeat: 2430 / 345

Going ahead to step 8:
When dividing 2430 by 345, we get 7 with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 125347.0
If we take 2415 away from 2430, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
345 can be fit into 150 0 times, resulting in a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 125347.0
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 10:
345 goes into 1500 4 times with a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 125347.04
Subtract 1380 from 1500 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 11:
The number 345 fits into 1200 3 times, leaving a remainder of 165.
Write down 3 as next digit of the result. 
Result so far: 125347.043
If we subtract 1035 from 1200, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 12:
If we divide 1650 by 345, we get 4 and a remainder of 270.
The number 4 becomes the next digit in our result. 
Result so far: 125347.0434
Subtract 1380 from 1650 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 13:
The number 345 fits into 2700 7 times, leaving a remainder of 285.
The number 7 becomes the next digit in our result. 
Result so far: 125347.04347
Deduct 2415 from 2700 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 14:
345 can be fit into 2850 8 times, resulting in a remainder of 90.
The number 8 becomes the next digit in our result. 
Result so far: 125347.043478
Subtract 2760 from 2850 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 15:
900 divided by 345 is 2 with a remainder of 210.
Record the quotient 2 as the next digit in the result. 
Result so far: 125347.0434782
The remainder is 210 after subtracting 690 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 16:
When dividing 2100 by 345, we get 6 with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 125347.04347826
If we subtract 2070 from 2100, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 125347.04347826, and the remainder is 3e-08.
