879334 divided by 86 
Our goal is to divide 879334 by 86.

Let's proceed to step 1:
86 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 86

On to 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
If we subtract 86 from 87, we get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 86

Let's proceed to step 3:
86 goes into 19 0 times with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 19 and we're left with 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 86

Advancing to step 4:
193 divided by 86 is 2 with a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 102.0
The remainder is 21 after subtracting 172 from 193.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 86

Moving on to step 5:
The number 86 fits into 213 2 times, leaving a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 1022.0
Deduct 172 from 213 and we're left with 41.
Fetch the next digit (4) from the dividend, attach it to 41 and continue: 414 / 86

Going ahead to step 6:
When dividing 414 by 86, we get 4 with a remainder of 70.
Record the quotient 4 as the next digit in the result. 
Result so far: 10224.0
Subtract 344 from 414 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.

Step 7:
The number 86 fits into 700 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 10224.8
Subtract 688 from 700 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
120 divided by 86 is 1 with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 10224.81
If we subtract 86 from 120, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
340 divided by 86 is 3 with a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 10224.813
Subtract 258 from 340 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 10:
The number 86 fits into 820 9 times, leaving a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 10224.8139
If we subtract 774 from 820, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 11:
460 divided by 86 is 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 10224.81395
Deduct 430 from 460 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
If we divide 300 by 86, we get 3 and a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 10224.813953
Subtract 258 from 300 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 13:
86 can be fit into 420 4 times, resulting in a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 10224.8139534
Subtract 344 from 420 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 14:
86 can be fit into 760 8 times, resulting in a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 10224.81395348
If we take 688 away from 760, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 10224.81395348, with a leftover of 7.2e-08.
