We look at the division of 42691586 by 396 
We want to divide 42691586 by 396.

Let's proceed to step 1:
If we divide 4 by 396, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 396

Let's proceed to step 2:
396 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 396

Going ahead to step 3:
396 can be fit into 426 1 times, resulting in a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 30 after subtracting 396 from 426.
Grab the next digit (9) from the dividend, add it to 30, then carry on: 309 / 396

Step 4:
The number 396 fits into 309 0 times, leaving a remainder of 309.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 309, we end up with 309.
Grab the next digit (1) from the dividend, add it to 309, then carry on: 3091 / 396

On to step 5:
If we divide 3091 by 396, we get 7 and a remainder of 319.
Use 7 as the next digit of our solution. 
Result so far: 107.0
Subtracting 2772 from 3091 leaves us with 319.
Append the next digit (5) from the dividend to 319 and continue with: 3195 / 396

Let's proceed to step 6:
396 goes into 3195 8 times with a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 1078.0
If we subtract 3168 from 3195, we get 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 396

Moving on to step 7:
The number 396 fits into 278 0 times, leaving a remainder of 278.
Put 0 as the next digit of the answer. 
Result so far: 10780.0
Subtract 0 from 278 to get 278.
Grab the next digit (6) from the dividend, add it to 278, then carry on: 2786 / 396

On to step 8:
If we divide 2786 by 396, we get 7 and a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 107807.0
Subtract 2772 from 2786 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
If we divide 140 by 396, we get 0 and a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 107807.0
If we subtract 0 from 140, we get 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:
If we divide 1400 by 396, we get 3 and a remainder of 212.
The number 3 becomes the next digit in our result. 
Result so far: 107807.03
Subtract 1188 from 1400 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 11:
396 can be fit into 2120 5 times, resulting in a remainder of 140.
Write down 5 as next digit of the result. 
Result so far: 107807.035
If we take 1980 away from 2120, we end up 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.

On to step 12:
When dividing 1400 by 396, we get 3 with a remainder of 212.
Write down 3 as next digit of the result. 
Result so far: 107807.0353
If we take 1188 away from 1400, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 13:
When dividing 2120 by 396, we get 5 with a remainder of 140.
Write down 5 as next digit of the result. 
Result so far: 107807.03535
Deduct 1980 from 2120 and we're left 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.

Let's proceed to step 14:
1400 divided by 396 is 3 with a remainder of 212.
Use 3 as the next digit of our solution. 
Result so far: 107807.035353
If we take 1188 away from 1400, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 15:
2120 divided by 396 is 5 with a remainder of 140.
Put 5 as the next digit of the answer. 
Result so far: 107807.0353535
If we subtract 1980 from 2120, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 16:
396 goes into 1400 3 times with a remainder of 212.
Write down 3 as next digit of the result. 
Result so far: 107807.03535353
If we subtract 1188 from 1400, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The final outcome is 107807.03535353, with a leftover of 2.12e-07.
