42645147 divided by 344 
We want to divide 42645147 by 344.

Advancing to step 1:
If we divide 4 by 344, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 344

Moving on to step 2:
344 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 344

Advancing to step 3:
The number 344 fits into 426 1 times, leaving a remainder of 82.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 344 away from 426, we end up with 82.
Include the next digit (4) from the dividend after 82, then repeat: 824 / 344

On to step 4:
824 divided by 344 is 2 with a remainder of 136.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 688 from 824, we get 136.
Grab the next digit (5) from the dividend, add it to 136, then carry on: 1365 / 344

Moving on to step 5:
When dividing 1365 by 344, we get 3 with a remainder of 333.
Put 3 as the next digit of the answer. 
Result so far: 123.0
If we take 1032 away from 1365, we end up with 333.
Fetch the next digit (1) from the dividend, attach it to 333 and continue: 3331 / 344

Advancing to step 6:
344 goes into 3331 9 times with a remainder of 235.
The number 9 becomes the next digit in our result. 
Result so far: 1239.0
The remainder is 235 after subtracting 3096 from 3331.
Include the next digit (4) from the dividend after 235, then repeat: 2354 / 344

Let's proceed to step 7:
If we divide 2354 by 344, we get 6 and a remainder of 290.
Use 6 as the next digit of our solution. 
Result so far: 12396.0
The remainder is 290 after subtracting 2064 from 2354.
Take the next digit (7) from the dividend and append it to 290, then repeat: 2907 / 344

Moving on to step 8:
2907 divided by 344 is 8 with a remainder of 155.
Use 8 as the next digit of our solution. 
Result so far: 123968.0
If we subtract 2752 from 2907, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 9:
344 goes into 1550 4 times with a remainder of 174.
Use 4 as the next digit of our solution. 
Result so far: 123968.4
Deduct 1376 from 1550 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 10:
The number 344 fits into 1740 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 123968.45
Deduct 1720 from 1740 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
200 divided by 344 is 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 123968.45
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 12:
2000 divided by 344 is 5 with a remainder of 280.
Use 5 as the next digit of our solution. 
Result so far: 123968.4505
If we take 1720 away from 2000, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 13:
When dividing 2800 by 344, we get 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 123968.45058
Subtract 2752 from 2800 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 14:
344 goes into 480 1 times with a remainder of 136.
Record the quotient 1 as the next digit in the result. 
Result so far: 123968.450581
If we take 344 away from 480, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 15:
The number 344 fits into 1360 3 times, leaving a remainder of 328.
Put 3 as the next digit of the answer. 
Result so far: 123968.4505813
If we subtract 1032 from 1360, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 16:
344 goes into 3280 9 times with a remainder of 184.
The next digit of our result is 9. 
Result so far: 123968.45058139
Subtract 3096 from 3280 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

In conclusion, the division gives 123968.45058139 with a balance of 1.84e-07.
