We look at the division of 19815587 by 312 
We're looking to find how many times 312 goes into 19815587.

On to step 1:
312 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 312

Step 2:
19 divided by 312 is 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 312

Step 3:
198 divided by 312 is 0 with a remainder of 198.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 198 after subtracting 0 from 198.
Grab the next digit (1) from the dividend, add it to 198, then carry on: 1981 / 312

Going ahead to step 4:
312 can be fit into 1981 6 times, resulting in a remainder of 109.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 109 after subtracting 1872 from 1981.
Fetch the next digit (5) from the dividend, attach it to 109 and continue: 1095 / 312

Moving on to step 5:
The number 312 fits into 1095 3 times, leaving a remainder of 159.
Write down 3 as next digit of the result. 
Result so far: 63.0
If we subtract 936 from 1095, we get 159.
Bring next digit (5) of the dividend behind the 159 and repeat the process: 1595 / 312

Moving on to step 6:
When dividing 1595 by 312, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 635.0
If we subtract 1560 from 1595, we get 35.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 312

On to step 7:
When dividing 358 by 312, we get 1 with a remainder of 46.
Record the quotient 1 as the next digit in the result. 
Result so far: 6351.0
Subtract 312 from 358 to get 46.
Grab the next digit (7) from the dividend, add it to 46, then carry on: 467 / 312

On to step 8:
If we divide 467 by 312, we get 1 and a remainder of 155.
Put 1 as the next digit of the answer. 
Result so far: 63511.0
If we take 312 away from 467, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 9:
312 can be fit into 1550 4 times, resulting in a remainder of 302.
Use 4 as the next digit of our solution. 
Result so far: 63511.4
Deduct 1248 from 1550 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Step 10:
The number 312 fits into 3020 9 times, leaving a remainder of 212.
Record the quotient 9 as the next digit in the result. 
Result so far: 63511.49
Subtracting 2808 from 3020 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 11:
312 goes into 2120 6 times with a remainder of 248.
Write down 6 as next digit of the result. 
Result so far: 63511.496
Subtracting 1872 from 2120 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 12:
312 goes into 2480 7 times with a remainder of 296.
Put 7 as the next digit of the answer. 
Result so far: 63511.4967
If we subtract 2184 from 2480, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 13:
2960 divided by 312 is 9 with a remainder of 152.
The number 9 becomes the next digit in our result. 
Result so far: 63511.49679
If we take 2808 away from 2960, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 14:
When dividing 1520 by 312, we get 4 with a remainder of 272.
Use 4 as the next digit of our solution. 
Result so far: 63511.496794
If we subtract 1248 from 1520, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 15:
If we divide 2720 by 312, we get 8 and a remainder of 224.
The number 8 becomes the next digit in our result. 
Result so far: 63511.4967948
Subtracting 2496 from 2720 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 16:
2240 divided by 312 is 7 with a remainder of 56.
Use 7 as the next digit of our solution. 
Result so far: 63511.49679487
Deduct 2184 from 2240 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 63511.49679487 and a remainder of 5.6e-08.
