Let's divide 851637 by 71
We're looking to find how many times 71 goes into 851637.

Let's proceed to step 1:
The number 71 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 71

On to step 2:
85 divided by 71 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 14 after subtracting 71 from 85.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 71

Going ahead to step 3:
141 divided by 71 is 1 with a remainder of 70.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 71 from 141 to get 70.
Grab the next digit (6) from the dividend, add it to 70, then carry on: 706 / 71

Moving on to step 4:
706 divided by 71 is 9 with a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
Subtract 639 from 706 to get 67.
Grab the next digit (3) from the dividend, add it to 67, then carry on: 673 / 71

Step 5:
673 divided by 71 is 9 with a remainder of 34.
The next digit of our result is 9. 
Result so far: 1199.0
Deduct 639 from 673 and we're left with 34.
Take the next digit (7) from the dividend and append it to 34, then repeat: 347 / 71

On to step 6:
If we divide 347 by 71, we get 4 and a remainder of 63.
Record the quotient 4 as the next digit in the result. 
Result so far: 11994.0
If we take 284 away from 347, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 7:
When dividing 630 by 71, we get 8 with a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 11994.8
Subtract 568 from 630 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 8:
71 can be fit into 620 8 times, resulting in a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 11994.88
Subtract 568 from 620 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 11994.88 with a remainder of 0.052.
