Let's divide 86719928 by 670
Let's see how many times 670 fits into 86719928.

Going ahead to step 1:
8 divided by 670 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 670

Advancing to step 2:
670 goes into 86 0 times with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (7) from the dividend, attach it to 86 and continue: 867 / 670

On to step 3:
867 divided by 670 is 1 with a remainder of 197.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 670 from 867, we get 197.
Include the next digit (1) from the dividend after 197, then repeat: 1971 / 670

Step 4:
If we divide 1971 by 670, we get 2 and a remainder of 631.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 1340 from 1971, we get 631.
Take the next digit (9) from the dividend and append it to 631, then repeat: 6319 / 670

Let's proceed to step 5:
The number 670 fits into 6319 9 times, leaving a remainder of 289.
Write down 9 as next digit of the result. 
Result so far: 129.0
Subtracting 6030 from 6319 leaves us with 289.
Append the next digit (9) from the dividend to 289 and continue with: 2899 / 670

Let's proceed to step 6:
2899 divided by 670 is 4 with a remainder of 219.
Write down 4 as next digit of the result. 
Result so far: 1294.0
If we subtract 2680 from 2899, we get 219.
Take the next digit (2) from the dividend and append it to 219, then repeat: 2192 / 670

Let's proceed to step 7:
670 goes into 2192 3 times with a remainder of 182.
Write down 3 as next digit of the result. 
Result so far: 12943.0
If we subtract 2010 from 2192, we get 182.
Grab the next digit (8) from the dividend, add it to 182, then carry on: 1828 / 670

Let's proceed to step 8:
The number 670 fits into 1828 2 times, leaving a remainder of 488.
The number 2 becomes the next digit in our result. 
Result so far: 129432.0
Subtract 1340 from 1828 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Going ahead to step 9:
670 goes into 4880 7 times with a remainder of 190.
The number 7 becomes the next digit in our result. 
Result so far: 129432.7
The remainder is 190 after subtracting 4690 from 4880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 10:
670 goes into 1900 2 times with a remainder of 560.
The next digit of our result is 2. 
Result so far: 129432.72
If we take 1340 away from 1900, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 11:
When dividing 5600 by 670, we get 8 with a remainder of 240.
Record the quotient 8 as the next digit in the result. 
Result so far: 129432.728
If we take 5360 away from 5600, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 12:
The number 670 fits into 2400 3 times, leaving a remainder of 390.
Use 3 as the next digit of our solution. 
Result so far: 129432.7283
Subtract 2010 from 2400 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 13:
When dividing 3900 by 670, we get 5 with a remainder of 550.
Put 5 as the next digit of the answer. 
Result so far: 129432.72835
Deduct 3350 from 3900 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Going ahead to step 14:
5500 divided by 670 is 8 with a remainder of 140.
Record the quotient 8 as the next digit in the result. 
Result so far: 129432.728358
If we take 5360 away from 5500, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 15:
1400 divided by 670 is 2 with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 129432.7283582
Deduct 1340 from 1400 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 16:
670 goes into 600 0 times with a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 129432.7283582
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Our division results in 129432.7283582 with a remaining 6e-07.
