We look at the division of 51701526 by 858 
We're looking to find how many times 858 goes into 51701526.

Advancing to step 1:
The number 858 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 858

On to step 2:
858 goes into 51 0 times with 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.
Bring next digit (7) of the dividend behind the 51 and repeat the process: 517 / 858

On to step 3:
858 goes into 517 0 times with a remainder of 517.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 517 leaves us with 517.
Grab the next digit (0) from the dividend, add it to 517, then carry on: 5170 / 858

Let's proceed to step 4:
When dividing 5170 by 858, we get 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 5148 from 5170 leaves us with 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 858

Going ahead to step 5:
The number 858 fits into 221 0 times, leaving a remainder of 221.
The next digit of our result is 0. 
Result so far: 60.0
Subtracting 0 from 221 leaves us with 221.
Append the next digit (5) from the dividend to 221 and continue with: 2215 / 858

Step 6:
858 can be fit into 2215 2 times, resulting in a remainder of 499.
The number 2 becomes the next digit in our result. 
Result so far: 602.0
If we subtract 1716 from 2215, we get 499.
Bring next digit (2) of the dividend behind the 499 and repeat the process: 4992 / 858

On to step 7:
4992 divided by 858 is 5 with a remainder of 702.
Record the quotient 5 as the next digit in the result. 
Result so far: 6025.0
Deduct 4290 from 4992 and we're left with 702.
Fetch the next digit (6) from the dividend, attach it to 702 and continue: 7026 / 858

Let's proceed to step 8:
When dividing 7026 by 858, we get 8 with a remainder of 162.
The next digit of our result is 8. 
Result so far: 60258.0
If we take 6864 away from 7026, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 9:
When dividing 1620 by 858, we get 1 with a remainder of 762.
Use 1 as the next digit of our solution. 
Result so far: 60258.1
Subtract 858 from 1620 to get 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Let's proceed to step 10:
The number 858 fits into 7620 8 times, leaving a remainder of 756.
The next digit of our result is 8. 
Result so far: 60258.18
Subtracting 6864 from 7620 leaves us with 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Step 11:
When dividing 7560 by 858, we get 8 with a remainder of 696.
The next digit of our result is 8. 
Result so far: 60258.188
The remainder is 696 after subtracting 6864 from 7560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

The quotient of the division is 60258.188, and the remainder is 0.0696.
