Let's divide 879610 by 86
We want to divide 879610 by 86.

Step 1:
86 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 86

Step 2:
If we divide 87 by 86, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 86 from 87 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 86

Advancing to step 3:
86 can be fit into 19 0 times, resulting in a remainder of 19.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 19 to get 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 86

Moving on to step 4:
If we divide 196 by 86, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 102.0
The remainder is 24 after subtracting 172 from 196.
Take the next digit (1) from the dividend and append it to 24, then repeat: 241 / 86

On to step 5:
86 can be fit into 241 2 times, resulting in a remainder of 69.
The next digit of our result is 2. 
Result so far: 1022.0
Deduct 172 from 241 and we're left with 69.
Fetch the next digit (0) from the dividend, attach it to 69 and continue: 690 / 86

Moving on to step 6:
When dividing 690 by 86, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 10228.0
If we take 688 away from 690, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
When dividing 20 by 86, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10228.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
The number 86 fits into 200 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 10228.02
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.

Advancing to step 9:
The number 86 fits into 280 3 times, leaving a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 10228.023
The remainder is 22 after subtracting 258 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
The number 86 fits into 220 2 times, leaving a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 10228.0232
If we take 172 away from 220, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
If we divide 480 by 86, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 10228.02325
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.

Going ahead to step 12:
500 divided by 86 is 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 10228.023255
Subtracting 430 from 500 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 10228.023255 with a remainder of 7e-06.
