We're dividing 421020 by 22 
We're looking to find how many times 22 goes into 421020.

Let's proceed to step 1:
22 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 22

Advancing to step 2:
If we divide 42 by 22, we get 1 and a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 22 from 42 to get 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 22

On to step 3:
The number 22 fits into 201 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 3 after subtracting 198 from 201.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 22

Step 4:
The number 22 fits into 30 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 191.0
The remainder is 8 after subtracting 22 from 30.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 22

Advancing to step 5:
When dividing 82 by 22, we get 3 with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 1913.0
Subtract 66 from 82 to get 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 22

Moving on to step 6:
If we divide 160 by 22, we get 7 and a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 19137.0
Deduct 154 from 160 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
22 goes into 60 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 19137.2
Subtracting 44 from 60 leaves us 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.

Let's proceed to step 8:
When dividing 160 by 22, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 19137.27
The remainder is 6 after subtracting 154 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
When dividing 60 by 22, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 19137.272
Subtracting 44 from 60 leaves us 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 10:
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: 19137.2727
The remainder is 6 after subtracting 154 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
When dividing 60 by 22, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 19137.27272
If we take 44 away from 60, 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.

Let's proceed to step 12:
22 goes into 160 7 times with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 19137.272727
If we take 154 away from 160, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
60 divided by 22 is 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 19137.2727272
Subtract 44 from 60 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
If we divide 160 by 22, we get 7 and a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 19137.27272727
Subtract 154 from 160 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 19137.27272727 with a remainder of 6e-09.
