We're dividing 51082616 by 396 
We want to divide 51082616 by 396.

Step 1:
When dividing 5 by 396, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 396

On to step 2:
The number 396 fits into 51 0 times, leaving a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 396

Step 3:
510 divided by 396 is 1 with a remainder of 114.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 396 from 510 to get 114.
Bring next digit (8) of the dividend behind the 114 and repeat the process: 1148 / 396

Step 4:
396 goes into 1148 2 times with a remainder of 356.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 792 from 1148 leaves us with 356.
Fetch the next digit (2) from the dividend, attach it to 356 and continue: 3562 / 396

Moving on to step 5:
If we divide 3562 by 396, we get 8 and a remainder of 394.
Use 8 as the next digit of our solution. 
Result so far: 128.0
If we take 3168 away from 3562, we end up with 394.
Take the next digit (6) from the dividend and append it to 394, then repeat: 3946 / 396

Let's proceed to step 6:
396 goes into 3946 9 times with a remainder of 382.
Put 9 as the next digit of the answer. 
Result so far: 1289.0
Subtract 3564 from 3946 to get 382.
Grab the next digit (1) from the dividend, add it to 382, then carry on: 3821 / 396

On to step 7:
396 can be fit into 3821 9 times, resulting in a remainder of 257.
Write down 9 as next digit of the result. 
Result so far: 12899.0
If we take 3564 away from 3821, we end up with 257.
Append the next digit (6) from the dividend to 257 and continue with: 2576 / 396

Moving on to step 8:
The number 396 fits into 2576 6 times, leaving a remainder of 200.
Use 6 as the next digit of our solution. 
Result so far: 128996.0
If we take 2376 away from 2576, 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 9:
The number 396 fits into 2000 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 128996.5
If we subtract 1980 from 2000, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
396 can be fit into 200 0 times, resulting in a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 128996.5
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 11:
396 goes into 2000 5 times with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 128996.505
Deduct 1980 from 2000 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.

On to step 12:
If we divide 200 by 396, we get 0 and a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 128996.505
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 13:
396 can be fit into 2000 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 128996.50505
Subtract 1980 from 2000 to get 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 14:
If we divide 200 by 396, we get 0 and a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 128996.50505
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 15:
396 goes into 2000 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 128996.5050505
If we subtract 1980 from 2000, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 16:
396 goes into 200 0 times with a remainder of 200.
The next digit of our result is 0. 
Result so far: 128996.5050505
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.

After the division, we end up with 128996.5050505 and a remainder of 2e-07.
