We look at the division of 20531115 by 336 
We want to figure out the number of times 20531115 can be divided by 336.

On to step 1:
336 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 336

Going ahead to step 2:
The number 336 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 336

Let's proceed to step 3:
336 goes into 205 0 times with a remainder of 205.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 205 leaves us with 205.
Include the next digit (3) from the dividend after 205, then repeat: 2053 / 336

Step 4:
If we divide 2053 by 336, we get 6 and a remainder of 37.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 2016 from 2053 leaves us with 37.
Fetch the next digit (1) from the dividend, attach it to 37 and continue: 371 / 336

Moving on to step 5:
If we divide 371 by 336, we get 1 and a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
Subtracting 336 from 371 leaves us with 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 336

Advancing to step 6:
When dividing 351 by 336, we get 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 611.0
Subtracting 336 from 351 leaves us with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 336

Advancing to step 7:
336 can be fit into 151 0 times, resulting in a remainder of 151.
The number 0 becomes the next digit in our result. 
Result so far: 6110.0
If we subtract 0 from 151, we get 151.
Append the next digit (5) from the dividend to 151 and continue with: 1515 / 336

Step 8:
When dividing 1515 by 336, we get 4 with a remainder of 171.
Use 4 as the next digit of our solution. 
Result so far: 61104.0
If we subtract 1344 from 1515, we get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 9:
336 goes into 1710 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 61104.5
Subtracting 1680 from 1710 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
336 can be fit into 300 0 times, resulting in a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 61104.5
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 11:
When dividing 3000 by 336, we get 8 with a remainder of 312.
Write down 8 as next digit of the result. 
Result so far: 61104.508
Deduct 2688 from 3000 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 12:
If we divide 3120 by 336, we get 9 and a remainder of 96.
The next digit of our result is 9. 
Result so far: 61104.5089
The remainder is 96 after subtracting 3024 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 13:
960 divided by 336 is 2 with a remainder of 288.
Write down 2 as next digit of the result. 
Result so far: 61104.50892
The remainder is 288 after subtracting 672 from 960.
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 14:
2880 divided by 336 is 8 with a remainder of 192.
Record the quotient 8 as the next digit in the result. 
Result so far: 61104.508928
If we subtract 2688 from 2880, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 15:
336 can be fit into 1920 5 times, resulting in a remainder of 240.
Use 5 as the next digit of our solution. 
Result so far: 61104.5089285
If we take 1680 away from 1920, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 16:
When dividing 2400 by 336, we get 7 with a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 61104.50892857
Subtracting 2352 from 2400 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 61104.50892857, and the remainder is 4.8e-08.
