We're dividing 789661 by 86 
We want to divide 789661 by 86.

Let's proceed to step 1:
The number 86 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 86

Advancing to step 2:
If we divide 78 by 86, we get 0 and a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Fetch the next digit (9) from the dividend, attach it to 78 and continue: 789 / 86

Step 3:
If we divide 789 by 86, we get 9 and a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 774 from 789 leaves us with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 86

On to step 4:
When dividing 156 by 86, we get 1 with a remainder of 70.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
Subtracting 86 from 156 leaves us with 70.
Grab the next digit (6) from the dividend, add it to 70, then carry on: 706 / 86

Moving on to step 5:
The number 86 fits into 706 8 times, leaving a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 918.0
Subtracting 688 from 706 leaves us with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 86

Moving on to step 6:
If we divide 181 by 86, we get 2 and a remainder of 9.
The next digit of our result is 2. 
Result so far: 9182.0
Subtracting 172 from 181 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
When dividing 90 by 86, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 9182.1
Subtracting 86 from 90 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
The number 86 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 9182.1
Subtracting 0 from 40 leaves us 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.

Going ahead to step 9:
86 goes into 400 4 times with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 9182.104
If we subtract 344 from 400, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
86 goes into 560 6 times with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 9182.1046
If we take 516 away from 560, we end up 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.

Let's proceed to step 11:
The number 86 fits into 440 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 9182.10465
If we take 430 away from 440, we end up 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.

Advancing to step 12:
86 goes into 100 1 times with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 9182.104651
Subtracting 86 from 100 leaves us with 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 13:
If we divide 140 by 86, we get 1 and a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 9182.1046511
Deduct 86 from 140 and we're left 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.

In conclusion, the division gives 9182.1046511 with a balance of 5.4e-07.
