21402 divided by 22 
Let's see how many times 22 fits into 21402.

Going ahead to step 1:
2 divided by 22 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 22

Step 2:
When dividing 21 by 22, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 22

Let's proceed to step 3:
When dividing 214 by 22, we get 9 with a remainder of 16.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 198 from 214, we get 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 22

Let's proceed to step 4:
22 can be fit into 160 7 times, resulting in a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
Subtract 154 from 160 to get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 22

Step 5:
The number 22 fits into 62 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 972.0
Subtracting 44 from 62 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 6:
The number 22 fits into 180 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 972.8
The remainder is 4 after subtracting 176 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
40 divided by 22 is 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 972.81
If we take 22 away from 40, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
If we divide 180 by 22, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 972.818
The remainder is 4 after subtracting 176 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
40 divided by 22 is 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 972.8181
Subtracting 22 from 40 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
The number 22 fits into 180 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 972.81818
Subtracting 176 from 180 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.

Advancing to step 11:
40 divided by 22 is 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 972.818181
If we take 22 away from 40, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
The number 22 fits into 180 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 972.8181818
Subtracting 176 from 180 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.

Step 13:
22 can be fit into 40 1 times, resulting in a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 972.81818181
The remainder is 18 after subtracting 22 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 972.81818181, and the remainder is 1.8e-08.
