We're dividing 42688983 by 353 
Our goal is to divide 42688983 by 353.

Step 1:
353 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 353

Moving on to step 2:
When dividing 42 by 353, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 353

Moving on to step 3:
The number 353 fits into 426 1 times, leaving a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 353 away from 426, we end up with 73.
Bring next digit (8) of the dividend behind the 73 and repeat the process: 738 / 353

Advancing to step 4:
When dividing 738 by 353, we get 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 706 from 738, we get 32.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 353

Step 5:
353 goes into 328 0 times with a remainder of 328.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
If we subtract 0 from 328, we get 328.
Fetch the next digit (9) from the dividend, attach it to 328 and continue: 3289 / 353

Step 6:
3289 divided by 353 is 9 with a remainder of 112.
Write down 9 as next digit of the result. 
Result so far: 1209.0
The remainder is 112 after subtracting 3177 from 3289.
Include the next digit (8) from the dividend after 112, then repeat: 1128 / 353

Step 7:
353 can be fit into 1128 3 times, resulting in a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 12093.0
Deduct 1059 from 1128 and we're left with 69.
Append the next digit (3) from the dividend to 69 and continue with: 693 / 353

Moving on to step 8:
353 can be fit into 693 1 times, resulting in a remainder of 340.
Use 1 as the next digit of our solution. 
Result so far: 120931.0
Deduct 353 from 693 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 9:
The number 353 fits into 3400 9 times, leaving a remainder of 223.
Put 9 as the next digit of the answer. 
Result so far: 120931.9
Deduct 3177 from 3400 and we're left with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

On to step 10:
353 can be fit into 2230 6 times, resulting in a remainder of 112.
The next digit of our result is 6. 
Result so far: 120931.96
If we take 2118 away from 2230, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 11:
353 can be fit into 1120 3 times, resulting in a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 120931.963
Subtracting 1059 from 1120 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 12:
353 goes into 610 1 times with a remainder of 257.
Write down 1 as next digit of the result. 
Result so far: 120931.9631
Deduct 353 from 610 and we're left with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Moving on to step 13:
If we divide 2570 by 353, we get 7 and a remainder of 99.
The next digit of our result is 7. 
Result so far: 120931.96317
If we take 2471 away from 2570, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 14:
353 goes into 990 2 times with a remainder of 284.
Write down 2 as next digit of the result. 
Result so far: 120931.963172
Deduct 706 from 990 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Advancing to step 15:
If we divide 2840 by 353, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 120931.9631728
If we subtract 2824 from 2840, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 16:
The number 353 fits into 160 0 times, leaving a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 120931.9631728
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 120931.9631728 with a remainder of 1.6e-07.
