Let's divide 42786224 by 345
We're looking to find how many times 345 goes into 42786224.

Advancing to step 1:
345 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 345

Moving on to step 2:
42 divided by 345 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 345

Moving on to step 3:
If we divide 427 by 345, we get 1 and a remainder of 82.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 345 from 427 to get 82.
Include the next digit (8) from the dividend after 82, then repeat: 828 / 345

Advancing to step 4:
345 goes into 828 2 times with a remainder of 138.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 690 from 828 to get 138.
Include the next digit (6) from the dividend after 138, then repeat: 1386 / 345

Step 5:
When dividing 1386 by 345, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 124.0
Deduct 1380 from 1386 and we're left with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 345

Going ahead to step 6:
345 goes into 62 0 times with a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 1240.0
If we subtract 0 from 62, we get 62.
Append the next digit (2) from the dividend to 62 and continue with: 622 / 345

Moving on to step 7:
345 goes into 622 1 times with a remainder of 277.
Record the quotient 1 as the next digit in the result. 
Result so far: 12401.0
The remainder is 277 after subtracting 345 from 622.
Include the next digit (4) from the dividend after 277, then repeat: 2774 / 345

Let's proceed to step 8:
When dividing 2774 by 345, we get 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 124018.0
Deduct 2760 from 2774 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
If we divide 140 by 345, we get 0 and a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 124018.0
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
1400 divided by 345 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 124018.04
Subtracting 1380 from 1400 leaves us 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.

Advancing to step 11:
345 can be fit into 200 0 times, resulting in a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 124018.04
If we take 0 away from 200, we end up 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.

Moving on to step 12:
When dividing 2000 by 345, we get 5 with a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 124018.0405
The remainder is 275 after subtracting 1725 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 13:
345 goes into 2750 7 times with a remainder of 335.
The next digit of our result is 7. 
Result so far: 124018.04057
If we take 2415 away from 2750, we end up with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 14:
3350 divided by 345 is 9 with a remainder of 245.
Use 9 as the next digit of our solution. 
Result so far: 124018.040579
Deduct 3105 from 3350 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Let's proceed to step 15:
2450 divided by 345 is 7 with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 124018.0405797
Deduct 2415 from 2450 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 16:
345 can be fit into 350 1 times, resulting in a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 124018.04057971
The remainder is 5 after subtracting 345 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 124018.04057971, and the remainder is 5e-09.
