Let's divide 113686 by 21
We're looking to find how many times 21 goes into 113686.

Let's proceed to step 1:
If we divide 1 by 21, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 21

On to step 2:
21 goes into 11 0 times with a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 21

Moving on to step 3:
The number 21 fits into 113 5 times, leaving a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 105 from 113 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 21

Let's proceed to step 4:
21 can be fit into 86 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
If we subtract 84 from 86, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 21

On to step 5:
The number 21 fits into 28 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 541.0
Subtract 21 from 28 to get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 21

Moving on to step 6:
The number 21 fits into 76 3 times, leaving a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 5413.0
Subtracting 63 from 76 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
When dividing 130 by 21, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 5413.6
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
40 divided by 21 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 5413.61
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
When dividing 190 by 21, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 5413.619
Deduct 189 from 190 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
If we divide 10 by 21, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 5413.619
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
21 can be fit into 100 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 5413.61904
If we take 84 away from 100, 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.

Advancing to step 12:
21 goes into 160 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 5413.619047
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 13:
If we divide 130 by 21, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 5413.6190476
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
When dividing 40 by 21, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 5413.61904761
Subtracting 21 from 40 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 5413.61904761, and the remainder is 1.9e-08.
