615742 divided by 86 
We want to figure out the number of times 615742 can be divided by 86.

Advancing to step 1:
6 divided by 86 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 86

Let's proceed to step 2:
61 divided by 86 is 0 with a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Include the next digit (5) from the dividend after 61, then repeat: 615 / 86

Going ahead to step 3:
If we divide 615 by 86, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 602 from 615, we get 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 86

Step 4:
If we divide 137 by 86, we get 1 and a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
If we subtract 86 from 137, we get 51.
Bring next digit (4) of the dividend behind the 51 and repeat the process: 514 / 86

On to step 5:
86 can be fit into 514 5 times, resulting in a remainder of 84.
Record the quotient 5 as the next digit in the result. 
Result so far: 715.0
If we subtract 430 from 514, we get 84.
Include the next digit (2) from the dividend after 84, then repeat: 842 / 86

Let's proceed to step 6:
When dividing 842 by 86, we get 9 with a remainder of 68.
The next digit of our result is 9. 
Result so far: 7159.0
The remainder is 68 after subtracting 774 from 842.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 7:
The number 86 fits into 680 7 times, leaving a remainder of 78.
The next digit of our result is 7. 
Result so far: 7159.7
If we subtract 602 from 680, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 8:
If we divide 780 by 86, we get 9 and a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 7159.79
If we subtract 774 from 780, we 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 9:
60 divided by 86 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 7159.79
Subtracting 0 from 60 leaves us 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.

Advancing to step 10:
The number 86 fits into 600 6 times, leaving a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 7159.7906
If we subtract 516 from 600, we 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.

Going ahead to step 11:
When dividing 840 by 86, we get 9 with a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 7159.79069
If we take 774 away from 840, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 12:
When dividing 660 by 86, we get 7 with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 7159.790697
If we subtract 602 from 660, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 13:
The number 86 fits into 580 6 times, leaving a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 7159.7906976
Deduct 516 from 580 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
When dividing 640 by 86, we get 7 with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 7159.79069767
Subtracting 602 from 640 leaves us 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.

In conclusion, the division gives 7159.79069767 with a balance of 3.8e-08.
