Let's divide 851615 by 71
Our goal is to divide 851615 by 71.

Let's proceed to step 1:
The number 71 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 71

Going ahead to step 2:
When dividing 85 by 71, we get 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 71 away from 85, we end up with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 71

On to step 3:
The number 71 fits into 141 1 times, leaving a remainder of 70.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 71 from 141 and we're left with 70.
Include the next digit (6) from the dividend after 70, then repeat: 706 / 71

Moving on to step 4:
When dividing 706 by 71, we get 9 with a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
The remainder is 67 after subtracting 639 from 706.
Grab the next digit (1) from the dividend, add it to 67, then carry on: 671 / 71

On to step 5:
If we divide 671 by 71, we get 9 and a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 1199.0
If we subtract 639 from 671, we get 32.
Append the next digit (5) from the dividend to 32 and continue with: 325 / 71

Moving on to step 6:
71 goes into 325 4 times with a remainder of 41.
The next digit of our result is 4. 
Result so far: 11994.0
Subtract 284 from 325 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 7:
When dividing 410 by 71, we get 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 11994.5
If we take 355 away from 410, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 8:
71 can be fit into 550 7 times, resulting in a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 11994.57
Subtract 497 from 550 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 9:
71 can be fit into 530 7 times, resulting in a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 11994.577
If we subtract 497 from 530, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final outcome is 11994.577, with a leftover of 0.0033.
