We're dividing 679402 by 86 
We're looking to find how many times 86 goes into 679402.

Step 1:
The number 86 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 86

Step 2:
The number 86 fits into 67 0 times, leaving a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Append the next digit (9) from the dividend to 67 and continue with: 679 / 86

On to step 3:
If we divide 679 by 86, we get 7 and a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 602 from 679 and we're left with 77.
Grab the next digit (4) from the dividend, add it to 77, then carry on: 774 / 86

Going ahead to step 4:
When dividing 774 by 86, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 79.0
The remainder is 0 after subtracting 774 from 774.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 86

Going ahead to step 5:
86 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 790.0
If we take 0 away from 0, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 86

Moving on to step 6:
If we divide 2 by 86, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 7900.0
Subtract 0 from 2 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.

Let's proceed to step 7:
If we divide 20 by 86, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 7900.0
If we subtract 0 from 20, we get 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:
If we divide 200 by 86, we get 2 and a remainder of 28.
The next digit of our result is 2. 
Result so far: 7900.02
Subtracting 172 from 200 leaves us with 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:
280 divided by 86 is 3 with a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 7900.023
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.

Let's proceed to step 10:
If we divide 220 by 86, we get 2 and a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 7900.0232
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.

On to step 11:
The number 86 fits into 480 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 7900.02325
If we take 430 away from 480, we end up 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.

Step 12:
If we divide 500 by 86, we get 5 and a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 7900.023255
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 outcome is 7900.023255, with a leftover of 7e-06.
