We divide 816891 by 51
Let's see how many times 51 fits into 816891.

Going ahead to step 1:
If we divide 8 by 51, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 51

Step 2:
51 goes into 81 1 times with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 51 away from 81, we end up with 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 51

On to step 3:
51 goes into 306 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 0 after subtracting 306 from 306.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 51

Advancing to step 4:
51 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 160.0
Subtract 0 from 8 to get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 51

Advancing to step 5:
89 divided by 51 is 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 1601.0
Subtracting 51 from 89 leaves us with 38.
Append the next digit (1) from the dividend to 38 and continue with: 381 / 51

Going ahead to step 6:
381 divided by 51 is 7 with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 16017.0
Subtracting 357 from 381 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
51 can be fit into 240 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 16017.4
The remainder is 36 after subtracting 204 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
When dividing 360 by 51, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 16017.47
If we subtract 357 from 360, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
When dividing 30 by 51, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 16017.47
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
300 divided by 51 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 16017.4705
Subtracting 255 from 300 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 11:
51 goes into 450 8 times with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 16017.47058
Deduct 408 from 450 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 12:
420 divided by 51 is 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 16017.470588
Subtracting 408 from 420 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 16017.470588, and the remainder is 1.2e-06.
