We look at the division of 53698101 by 312 
Our goal is to divide 53698101 by 312.

Let's proceed to step 1:
When dividing 5 by 312, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 312

Advancing to step 2:
53 divided by 312 is 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Grab the next digit (6) from the dividend, add it to 53, then carry on: 536 / 312

Going ahead to step 3:
312 goes into 536 1 times with a remainder of 224.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 312 from 536, we get 224.
Include the next digit (9) from the dividend after 224, then repeat: 2249 / 312

Moving on to step 4:
312 can be fit into 2249 7 times, resulting in a remainder of 65.
The next digit of our result is 7. 
Result so far: 17.0
If we take 2184 away from 2249, we end up with 65.
Include the next digit (8) from the dividend after 65, then repeat: 658 / 312

Advancing to step 5:
The number 312 fits into 658 2 times, leaving a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 172.0
The remainder is 34 after subtracting 624 from 658.
Bring next digit (1) of the dividend behind the 34 and repeat the process: 341 / 312

Step 6:
If we divide 341 by 312, we get 1 and a remainder of 29.
The next digit of our result is 1. 
Result so far: 1721.0
The remainder is 29 after subtracting 312 from 341.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 312

Let's proceed to step 7:
312 can be fit into 290 0 times, resulting in a remainder of 290.
Write down 0 as next digit of the result. 
Result so far: 17210.0
The remainder is 290 after subtracting 0 from 290.
Fetch the next digit (1) from the dividend, attach it to 290 and continue: 2901 / 312

On to step 8:
The number 312 fits into 2901 9 times, leaving a remainder of 93.
The number 9 becomes the next digit in our result. 
Result so far: 172109.0
Subtract 2808 from 2901 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Moving on to step 9:
312 can be fit into 930 2 times, resulting in a remainder of 306.
Write down 2 as next digit of the result. 
Result so far: 172109.2
If we subtract 624 from 930, we get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 10:
If we divide 3060 by 312, we get 9 and a remainder of 252.
The next digit of our result is 9. 
Result so far: 172109.29
If we take 2808 away from 3060, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 11:
When dividing 2520 by 312, we get 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 172109.298
Deduct 2496 from 2520 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
240 divided by 312 is 0 with a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 172109.298
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 13:
2400 divided by 312 is 7 with a remainder of 216.
The number 7 becomes the next digit in our result. 
Result so far: 172109.29807
If we take 2184 away from 2400, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 14:
2160 divided by 312 is 6 with a remainder of 288.
Record the quotient 6 as the next digit in the result. 
Result so far: 172109.298076
If we take 1872 away from 2160, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 15:
312 goes into 2880 9 times with a remainder of 72.
Use 9 as the next digit of our solution. 
Result so far: 172109.2980769
If we subtract 2808 from 2880, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 16:
If we divide 720 by 312, we get 2 and a remainder of 96.
The next digit of our result is 2. 
Result so far: 172109.29807692
If we subtract 624 from 720, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

After the division, we end up with 172109.29807692 and a remainder of 9.6e-08.
