31210555 divided by 808 
We're looking to find how many times 808 goes into 31210555.

Advancing to step 1:
808 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 808

Advancing to step 2:
When dividing 31 by 808, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 808

Going ahead to step 3:
808 can be fit into 312 0 times, resulting in a remainder of 312.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 312 to get 312.
Include the next digit (1) from the dividend after 312, then repeat: 3121 / 808

Step 4:
The number 808 fits into 3121 3 times, leaving a remainder of 697.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 697 after subtracting 2424 from 3121.
Append the next digit (0) from the dividend to 697 and continue with: 6970 / 808

On to step 5:
If we divide 6970 by 808, we get 8 and a remainder of 506.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we take 6464 away from 6970, we end up with 506.
Grab the next digit (5) from the dividend, add it to 506, then carry on: 5065 / 808

Going ahead to step 6:
5065 divided by 808 is 6 with a remainder of 217.
The next digit of our result is 6. 
Result so far: 386.0
If we take 4848 away from 5065, we end up with 217.
Append the next digit (5) from the dividend to 217 and continue with: 2175 / 808

Step 7:
808 can be fit into 2175 2 times, resulting in a remainder of 559.
Record the quotient 2 as the next digit in the result. 
Result so far: 3862.0
If we subtract 1616 from 2175, we get 559.
Take the next digit (5) from the dividend and append it to 559, then repeat: 5595 / 808

On to step 8:
The number 808 fits into 5595 6 times, leaving a remainder of 747.
Use 6 as the next digit of our solution. 
Result so far: 38626.0
If we take 4848 away from 5595, we end up with 747.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7470, and continue the process.

Going ahead to step 9:
When dividing 7470 by 808, we get 9 with a remainder of 198.
The number 9 becomes the next digit in our result. 
Result so far: 38626.9
Subtracting 7272 from 7470 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 10:
The number 808 fits into 1980 2 times, leaving a remainder of 364.
Record the quotient 2 as the next digit in the result. 
Result so far: 38626.92
The remainder is 364 after subtracting 1616 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 11:
If we divide 3640 by 808, we get 4 and a remainder of 408.
The number 4 becomes the next digit in our result. 
Result so far: 38626.924
If we take 3232 away from 3640, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Let's proceed to step 12:
808 can be fit into 4080 5 times, resulting in a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 38626.9245
Deduct 4040 from 4080 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
If we divide 400 by 808, we get 0 and a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 38626.9245
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 14:
808 can be fit into 4000 4 times, resulting in a remainder of 768.
Record the quotient 4 as the next digit in the result. 
Result so far: 38626.924504
Subtract 3232 from 4000 to get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Let's proceed to step 15:
808 can be fit into 7680 9 times, resulting in a remainder of 408.
Write down 9 as next digit of the result. 
Result so far: 38626.9245049
Deduct 7272 from 7680 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 16:
The number 808 fits into 4080 5 times, leaving a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 38626.92450495
Deduct 4040 from 4080 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 38626.92450495, with a leftover of 4e-08.
