We look at the division of 113336 by 21 
We want to figure out the number of times 113336 can be divided by 21.

Step 1:
21 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 21

Step 2:
If we divide 11 by 21, we get 0 and a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 21

Let's proceed to step 3:
The number 21 fits into 113 5 times, leaving a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 105 from 113 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 21

Going ahead to step 4:
The number 21 fits into 83 3 times, leaving a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 53.0
Subtracting 63 from 83 leaves us with 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 21

Step 5:
The number 21 fits into 203 9 times, leaving a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 539.0
Subtracting 189 from 203 leaves us with 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 21

Let's proceed to step 6:
When dividing 146 by 21, we get 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 5396.0
Deduct 126 from 146 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 5396.9
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 8:
21 can be fit into 110 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5396.95
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
50 divided by 21 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 5396.952
Subtracting 42 from 50 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
When dividing 80 by 21, we get 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 5396.9523
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 11:
If we divide 170 by 21, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 5396.95238
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
21 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 5396.95238
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
When dividing 200 by 21, we get 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 5396.9523809
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 14:
If we divide 110 by 21, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 5396.95238095
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 5396.95238095 and a remainder of 5e-09.
