51535556 ÷ 856 
We want to figure out the number of times 51535556 can be divided by 856.

Going ahead to step 1:
5 divided by 856 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 856

Going ahead to step 2:
856 can be fit into 51 0 times, resulting in a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 856

Moving on to step 3:
856 goes into 515 0 times with a remainder of 515.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 515 and we're left with 515.
Grab the next digit (3) from the dividend, add it to 515, then carry on: 5153 / 856

Step 4:
856 goes into 5153 6 times with a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 5136 away from 5153, we end up with 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 856

Step 5:
856 can be fit into 175 0 times, resulting in a remainder of 175.
Put 0 as the next digit of the answer. 
Result so far: 60.0
If we subtract 0 from 175, we get 175.
Bring next digit (5) of the dividend behind the 175 and repeat the process: 1755 / 856

Let's proceed to step 6:
The number 856 fits into 1755 2 times, leaving a remainder of 43.
Write down 2 as next digit of the result. 
Result so far: 602.0
The remainder is 43 after subtracting 1712 from 1755.
Append the next digit (5) from the dividend to 43 and continue with: 435 / 856

Going ahead to step 7:
856 goes into 435 0 times with a remainder of 435.
Record the quotient 0 as the next digit in the result. 
Result so far: 6020.0
If we subtract 0 from 435, we get 435.
Include the next digit (6) from the dividend after 435, then repeat: 4356 / 856

Advancing to step 8:
856 goes into 4356 5 times with a remainder of 76.
Put 5 as the next digit of the answer. 
Result so far: 60205.0
If we take 4280 away from 4356, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 9:
856 goes into 760 0 times with a remainder of 760.
The number 0 becomes the next digit in our result. 
Result so far: 60205.0
Subtract 0 from 760 to get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Let's proceed to step 10:
856 can be fit into 7600 8 times, resulting in a remainder of 752.
Record the quotient 8 as the next digit in the result. 
Result so far: 60205.08
If we take 6848 away from 7600, we end up with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Advancing to step 11:
If we divide 7520 by 856, we get 8 and a remainder of 672.
Write down 8 as next digit of the result. 
Result so far: 60205.088
Subtracting 6848 from 7520 leaves us with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

The final result is 60205.088 with a remainder of 0.0672.
