We look at the division of 761780 by 86 
Our goal is to divide 761780 by 86.

On to step 1:
86 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 86

On to step 2:
The number 86 fits into 76 0 times, leaving a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Bring next digit (1) of the dividend behind the 76 and repeat the process: 761 / 86

Advancing to step 3:
If we divide 761 by 86, we get 8 and a remainder of 73.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 688 from 761 to get 73.
Append the next digit (7) from the dividend to 73 and continue with: 737 / 86

On to step 4:
The number 86 fits into 737 8 times, leaving a remainder of 49.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
If we subtract 688 from 737, we get 49.
Append the next digit (8) from the dividend to 49 and continue with: 498 / 86

Advancing to step 5:
If we divide 498 by 86, we get 5 and a remainder of 68.
Use 5 as the next digit of our solution. 
Result so far: 885.0
The remainder is 68 after subtracting 430 from 498.
Take the next digit (0) from the dividend and append it to 68, then repeat: 680 / 86

Let's proceed to step 6:
If we divide 680 by 86, we get 7 and a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 8857.0
Subtracting 602 from 680 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 7:
If we divide 780 by 86, we get 9 and a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 8857.9
Subtract 774 from 780 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
When dividing 60 by 86, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 8857.9
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
The number 86 fits into 600 6 times, leaving a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 8857.906
Subtract 516 from 600 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 10:
The number 86 fits into 840 9 times, leaving a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 8857.9069
If we subtract 774 from 840, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 11:
When dividing 660 by 86, we get 7 with a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 8857.90697
If we take 602 away from 660, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 12:
86 goes into 580 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 8857.906976
If we subtract 516 from 580, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
The number 86 fits into 640 7 times, leaving a remainder of 38.
The next digit of our result is 7. 
Result so far: 8857.9069767
Deduct 602 from 640 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
86 goes into 380 4 times with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 8857.90697674
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 8857.90697674 with a remaining 3.6e-08.
