We divide 80205311 by 610
We want to figure out the number of times 80205311 can be divided by 610.

On to step 1:
When dividing 8 by 610, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 610

Let's proceed to step 2:
The number 610 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Include the next digit (2) from the dividend after 80, then repeat: 802 / 610

Advancing to step 3:
610 goes into 802 1 times with a remainder of 192.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 610 from 802, we get 192.
Bring next digit (0) of the dividend behind the 192 and repeat the process: 1920 / 610

Advancing to step 4:
610 goes into 1920 3 times with a remainder of 90.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 1830 from 1920, we get 90.
Include the next digit (5) from the dividend after 90, then repeat: 905 / 610

Let's proceed to step 5:
When dividing 905 by 610, we get 1 with a remainder of 295.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
The remainder is 295 after subtracting 610 from 905.
Append the next digit (3) from the dividend to 295 and continue with: 2953 / 610

Advancing to step 6:
2953 divided by 610 is 4 with a remainder of 513.
Put 4 as the next digit of the answer. 
Result so far: 1314.0
Deduct 2440 from 2953 and we're left with 513.
Include the next digit (1) from the dividend after 513, then repeat: 5131 / 610

Let's proceed to step 7:
5131 divided by 610 is 8 with a remainder of 251.
The next digit of our result is 8. 
Result so far: 13148.0
The remainder is 251 after subtracting 4880 from 5131.
Fetch the next digit (1) from the dividend, attach it to 251 and continue: 2511 / 610

Moving on to step 8:
610 can be fit into 2511 4 times, resulting in a remainder of 71.
The number 4 becomes the next digit in our result. 
Result so far: 131484.0
Deduct 2440 from 2511 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 9:
The number 610 fits into 710 1 times, leaving a remainder of 100.
Use 1 as the next digit of our solution. 
Result so far: 131484.1
If we subtract 610 from 710, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 10:
610 can be fit into 1000 1 times, resulting in a remainder of 390.
The next digit of our result is 1. 
Result so far: 131484.11
If we subtract 610 from 1000, we 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.

The quotient of the division is 131484.11, and the remainder is 0.39.
