We look at the division of 81988204 by 312 
We're looking to find how many times 312 goes into 81988204.

Step 1:
If we divide 8 by 312, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 312

Moving on to step 2:
312 can be fit into 81 0 times, resulting in a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 312

Let's proceed to step 3:
312 goes into 819 2 times with a remainder of 195.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 624 away from 819, we end up with 195.
Fetch the next digit (8) from the dividend, attach it to 195 and continue: 1958 / 312

Let's proceed to step 4:
1958 divided by 312 is 6 with a remainder of 86.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we subtract 1872 from 1958, we get 86.
Grab the next digit (8) from the dividend, add it to 86, then carry on: 868 / 312

Step 5:
When dividing 868 by 312, we get 2 with a remainder of 244.
Record the quotient 2 as the next digit in the result. 
Result so far: 262.0
If we take 624 away from 868, we end up with 244.
Grab the next digit (2) from the dividend, add it to 244, then carry on: 2442 / 312

Moving on to step 6:
312 goes into 2442 7 times with a remainder of 258.
The number 7 becomes the next digit in our result. 
Result so far: 2627.0
If we take 2184 away from 2442, we end up with 258.
Grab the next digit (0) from the dividend, add it to 258, then carry on: 2580 / 312

Going ahead to step 7:
When dividing 2580 by 312, we get 8 with a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 26278.0
Subtract 2496 from 2580 to get 84.
Include the next digit (4) from the dividend after 84, then repeat: 844 / 312

On to step 8:
844 divided by 312 is 2 with a remainder of 220.
The next digit of our result is 2. 
Result so far: 262782.0
The remainder is 220 after subtracting 624 from 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 9:
When dividing 2200 by 312, we get 7 with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 262782.7
The remainder is 16 after subtracting 2184 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
312 can be fit into 160 0 times, resulting in a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 262782.7
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 11:
The number 312 fits into 1600 5 times, leaving a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 262782.705
Subtracting 1560 from 1600 leaves us 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.

On to step 12:
312 goes into 400 1 times with a remainder of 88.
The next digit of our result is 1. 
Result so far: 262782.7051
The remainder is 88 after subtracting 312 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 13:
When dividing 880 by 312, we get 2 with a remainder of 256.
Write down 2 as next digit of the result. 
Result so far: 262782.70512
If we take 624 away from 880, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 14:
The number 312 fits into 2560 8 times, leaving a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 262782.705128
Subtracting 2496 from 2560 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 15:
If we divide 640 by 312, we get 2 and a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 262782.7051282
If we take 624 away from 640, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 16:
312 can be fit into 160 0 times, resulting in a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 262782.7051282
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

After the division, we end up with 262782.7051282 and a remainder of 1.6e-07.
