Let's divide 86036493 by 621
We're looking to find how many times 621 goes into 86036493.

Step 1:
8 divided by 621 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 621

Advancing to step 2:
621 goes into 86 0 times with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Bring next digit (0) of the dividend behind the 86 and repeat the process: 860 / 621

On to step 3:
860 divided by 621 is 1 with a remainder of 239.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 621 away from 860, we end up with 239.
Grab the next digit (3) from the dividend, add it to 239, then carry on: 2393 / 621

Advancing to step 4:
The number 621 fits into 2393 3 times, leaving a remainder of 530.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 1863 from 2393 to get 530.
Fetch the next digit (6) from the dividend, attach it to 530 and continue: 5306 / 621

Advancing to step 5:
If we divide 5306 by 621, we get 8 and a remainder of 338.
The number 8 becomes the next digit in our result. 
Result so far: 138.0
The remainder is 338 after subtracting 4968 from 5306.
Grab the next digit (4) from the dividend, add it to 338, then carry on: 3384 / 621

Moving on to step 6:
621 goes into 3384 5 times with a remainder of 279.
The number 5 becomes the next digit in our result. 
Result so far: 1385.0
Subtracting 3105 from 3384 leaves us with 279.
Include the next digit (9) from the dividend after 279, then repeat: 2799 / 621

Moving on to step 7:
When dividing 2799 by 621, we get 4 with a remainder of 315.
The number 4 becomes the next digit in our result. 
Result so far: 13854.0
If we take 2484 away from 2799, we end up with 315.
Take the next digit (3) from the dividend and append it to 315, then repeat: 3153 / 621

Let's proceed to step 8:
When dividing 3153 by 621, we get 5 with a remainder of 48.
The next digit of our result is 5. 
Result so far: 138545.0
Subtract 3105 from 3153 to 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 9:
If we divide 480 by 621, we get 0 and a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 138545.0
Subtract 0 from 480 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 10:
The number 621 fits into 4800 7 times, leaving a remainder of 453.
Record the quotient 7 as the next digit in the result. 
Result so far: 138545.07
If we subtract 4347 from 4800, we get 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Advancing to step 11:
If we divide 4530 by 621, we get 7 and a remainder of 183.
Record the quotient 7 as the next digit in the result. 
Result so far: 138545.077
The remainder is 183 after subtracting 4347 from 4530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

The final result is 138545.077 with a remainder of 0.0183.
