We're dividing 51997789 by 856 
We're looking to find how many times 856 goes into 51997789.

Going ahead to step 1:
The number 856 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 856

Step 2:
If we divide 51 by 856, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Fetch the next digit (9) from the dividend, attach it to 51 and continue: 519 / 856

Moving on to step 3:
856 goes into 519 0 times with a remainder of 519.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 519 and we're left with 519.
Take the next digit (9) from the dividend and append it to 519, then repeat: 5199 / 856

Advancing to step 4:
When dividing 5199 by 856, we get 6 with a remainder of 63.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 5136 from 5199 and we're left with 63.
Fetch the next digit (7) from the dividend, attach it to 63 and continue: 637 / 856

Let's proceed to step 5:
637 divided by 856 is 0 with a remainder of 637.
Write down 0 as next digit of the result. 
Result so far: 60.0
If we take 0 away from 637, we end up with 637.
Bring next digit (7) of the dividend behind the 637 and repeat the process: 6377 / 856

Advancing to step 6:
6377 divided by 856 is 7 with a remainder of 385.
The next digit of our result is 7. 
Result so far: 607.0
Subtract 5992 from 6377 to get 385.
Grab the next digit (8) from the dividend, add it to 385, then carry on: 3858 / 856

Let's proceed to step 7:
856 goes into 3858 4 times with a remainder of 434.
Use 4 as the next digit of our solution. 
Result so far: 6074.0
Deduct 3424 from 3858 and we're left with 434.
Append the next digit (9) from the dividend to 434 and continue with: 4349 / 856

Let's proceed to step 8:
856 goes into 4349 5 times with a remainder of 69.
Put 5 as the next digit of the answer. 
Result so far: 60745.0
Deduct 4280 from 4349 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 9:
If we divide 690 by 856, we get 0 and a remainder of 690.
Record the quotient 0 as the next digit in the result. 
Result so far: 60745.0
Deduct 0 from 690 and we're left with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Step 10:
If we divide 6900 by 856, we get 8 and a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 60745.08
Deduct 6848 from 6900 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 11:
856 can be fit into 520 0 times, resulting in a remainder of 520.
Write down 0 as next digit of the result. 
Result so far: 60745.08
Subtract 0 from 520 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 12:
856 can be fit into 5200 6 times, resulting in a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 60745.0806
Deduct 5136 from 5200 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
856 can be fit into 640 0 times, resulting in a remainder of 640.
The number 0 becomes the next digit in our result. 
Result so far: 60745.0806
The remainder is 640 after subtracting 0 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 14:
The number 856 fits into 6400 7 times, leaving a remainder of 408.
The next digit of our result is 7. 
Result so far: 60745.080607
The remainder is 408 after subtracting 5992 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 15:
When dividing 4080 by 856, we get 4 with a remainder of 656.
Write down 4 as next digit of the result. 
Result so far: 60745.0806074
Deduct 3424 from 4080 and we're left with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Going ahead to step 16:
The number 856 fits into 6560 7 times, leaving a remainder of 568.
The next digit of our result is 7. 
Result so far: 60745.08060747
If we subtract 5992 from 6560, we get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

The final outcome is 60745.08060747, with a leftover of 5.68e-07.
