We divide 851010 by 86
We want to divide 851010 by 86.

Let's proceed to step 1:
8 divided by 86 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 86

Step 2:
The number 86 fits into 85 0 times, leaving a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Append the next digit (1) from the dividend to 85 and continue with: 851 / 86

Moving on to step 3:
851 divided by 86 is 9 with a remainder of 77.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 774 from 851 and we're left with 77.
Grab the next digit (0) from the dividend, add it to 77, then carry on: 770 / 86

Moving on to step 4:
86 goes into 770 8 times with a remainder of 82.
Use 8 as the next digit of our solution. 
Result so far: 98.0
If we take 688 away from 770, we end up with 82.
Include the next digit (1) from the dividend after 82, then repeat: 821 / 86

Advancing to step 5:
The number 86 fits into 821 9 times, leaving a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 989.0
Deduct 774 from 821 and we're left with 47.
Include the next digit (0) from the dividend after 47, then repeat: 470 / 86

Step 6:
When dividing 470 by 86, we get 5 with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 9895.0
Deduct 430 from 470 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
400 divided by 86 is 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 9895.4
The remainder is 56 after subtracting 344 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 8:
86 goes into 560 6 times with a remainder of 44.
The next digit of our result is 6. 
Result so far: 9895.46
Deduct 516 from 560 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
The number 86 fits into 440 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 9895.465
Subtracting 430 from 440 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
The number 86 fits into 100 1 times, leaving a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 9895.4651
If we subtract 86 from 100, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
If we divide 140 by 86, we get 1 and a remainder of 54.
The next digit of our result is 1. 
Result so far: 9895.46511
Subtracting 86 from 140 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 9895.46511 with a remainder of 5.4e-05.
