We look at the division of 86130346 by 670 
We're looking to find how many times 670 goes into 86130346.

Advancing to step 1:
670 can be fit into 8 0 times, resulting in 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.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 670

Advancing to step 2:
670 can be fit into 86 0 times, resulting in a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Take the next digit (1) from the dividend and append it to 86, then repeat: 861 / 670

On to step 3:
670 goes into 861 1 times with a remainder of 191.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 670 from 861 to get 191.
Append the next digit (3) from the dividend to 191 and continue with: 1913 / 670

Let's proceed to step 4:
1913 divided by 670 is 2 with a remainder of 573.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 1340 from 1913 leaves us with 573.
Append the next digit (0) from the dividend to 573 and continue with: 5730 / 670

Moving on to step 5:
5730 divided by 670 is 8 with a remainder of 370.
Write down 8 as next digit of the result. 
Result so far: 128.0
The remainder is 370 after subtracting 5360 from 5730.
Append the next digit (3) from the dividend to 370 and continue with: 3703 / 670

On to step 6:
3703 divided by 670 is 5 with a remainder of 353.
The next digit of our result is 5. 
Result so far: 1285.0
The remainder is 353 after subtracting 3350 from 3703.
Fetch the next digit (4) from the dividend, attach it to 353 and continue: 3534 / 670

On to step 7:
The number 670 fits into 3534 5 times, leaving a remainder of 184.
Put 5 as the next digit of the answer. 
Result so far: 12855.0
Subtract 3350 from 3534 to get 184.
Grab the next digit (6) from the dividend, add it to 184, then carry on: 1846 / 670

Let's proceed to step 8:
1846 divided by 670 is 2 with a remainder of 506.
Use 2 as the next digit of our solution. 
Result so far: 128552.0
If we subtract 1340 from 1846, we get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Step 9:
When dividing 5060 by 670, we get 7 with a remainder of 370.
Put 7 as the next digit of the answer. 
Result so far: 128552.7
If we take 4690 away from 5060, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 10:
670 goes into 3700 5 times with a remainder of 350.
Write down 5 as next digit of the result. 
Result so far: 128552.75
Deduct 3350 from 3700 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 11:
3500 divided by 670 is 5 with a remainder of 150.
The next digit of our result is 5. 
Result so far: 128552.755
If we subtract 3350 from 3500, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The final outcome is 128552.755, with a leftover of 0.015.
