8257918 divided by 86 
We want to figure out the number of times 8257918 can be divided by 86.

Going ahead to step 1:
The number 86 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 86

Going ahead to step 2:
When dividing 82 by 86, we get 0 with a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Include the next digit (5) from the dividend after 82, then repeat: 825 / 86

Going ahead to step 3:
The number 86 fits into 825 9 times, leaving a remainder of 51.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 774 from 825 and we're left with 51.
Grab the next digit (7) from the dividend, add it to 51, then carry on: 517 / 86

Advancing to step 4:
The number 86 fits into 517 6 times, leaving a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
Subtracting 516 from 517 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 86

Advancing to step 5:
19 divided by 86 is 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 960.0
Deduct 0 from 19 and we're left with 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 86

Going ahead to step 6:
191 divided by 86 is 2 with a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 9602.0
Deduct 172 from 191 and we're left with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 86

Moving on to step 7:
When dividing 198 by 86, we get 2 with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 96022.0
The remainder is 26 after subtracting 172 from 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
When dividing 260 by 86, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 96022.3
Subtract 258 from 260 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
86 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 96022.3
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
86 goes into 200 2 times with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 96022.302
Subtract 172 from 200 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
86 can be fit into 280 3 times, resulting in a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 96022.3023
If we take 258 away from 280, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
The number 86 fits into 220 2 times, leaving a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 96022.30232
If we subtract 172 from 220, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
86 goes into 480 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 96022.302325
Subtracting 430 from 480 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 14:
86 goes into 500 5 times with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 96022.3023255
Subtract 430 from 500 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 96022.3023255 with a balance of 7e-07.
