We look at the division of 86726219 by 620 
Let's see how many times 620 fits into 86726219.

Step 1:
620 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
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 / 620

Advancing to step 2:
620 can be fit into 86 0 times, resulting in a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Grab the next digit (7) from the dividend, add it to 86, then carry on: 867 / 620

On to step 3:
620 goes into 867 1 times with a remainder of 247.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 620 from 867 and we're left with 247.
Take the next digit (2) from the dividend and append it to 247, then repeat: 2472 / 620

Advancing to step 4:
620 can be fit into 2472 3 times, resulting in a remainder of 612.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 612 after subtracting 1860 from 2472.
Bring next digit (6) of the dividend behind the 612 and repeat the process: 6126 / 620

Moving on to step 5:
620 can be fit into 6126 9 times, resulting in a remainder of 546.
Put 9 as the next digit of the answer. 
Result so far: 139.0
If we take 5580 away from 6126, we end up with 546.
Append the next digit (2) from the dividend to 546 and continue with: 5462 / 620

Moving on to step 6:
If we divide 5462 by 620, we get 8 and a remainder of 502.
Record the quotient 8 as the next digit in the result. 
Result so far: 1398.0
If we take 4960 away from 5462, we end up with 502.
Fetch the next digit (1) from the dividend, attach it to 502 and continue: 5021 / 620

On to step 7:
If we divide 5021 by 620, we get 8 and a remainder of 61.
The number 8 becomes the next digit in our result. 
Result so far: 13988.0
Subtracting 4960 from 5021 leaves us with 61.
Fetch the next digit (9) from the dividend, attach it to 61 and continue: 619 / 620

Let's proceed to step 8:
620 goes into 619 0 times with a remainder of 619.
Use 0 as the next digit of our solution. 
Result so far: 139880.0
The remainder is 619 after subtracting 0 from 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

On to step 9:
620 can be fit into 6190 9 times, resulting in a remainder of 610.
The number 9 becomes the next digit in our result. 
Result so far: 139880.9
Deduct 5580 from 6190 and we're left with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Moving on to step 10:
620 can be fit into 6100 9 times, resulting in a remainder of 520.
Record the quotient 9 as the next digit in the result. 
Result so far: 139880.99
If we take 5580 away from 6100, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

The final result is 139880.99 with a remainder of 0.52.
