421999 divided by 22 
Our goal is to divide 421999 by 22.

On to step 1:
4 divided by 22 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 22

Advancing to step 2:
42 divided by 22 is 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 22 from 42 leaves us with 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 22

Let's proceed to step 3:
When dividing 201 by 22, we get 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtracting 198 from 201 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 22

Advancing to step 4:
The number 22 fits into 39 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 191.0
If we take 22 away from 39, we end up with 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 22

On to step 5:
22 can be fit into 179 8 times, resulting in a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 1918.0
Subtracting 176 from 179 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 22

Advancing to step 6:
The number 22 fits into 39 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 19181.0
Subtracting 22 from 39 leaves us 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.

Advancing to step 7:
170 divided by 22 is 7 with a remainder of 16.
The next digit of our result is 7. 
Result so far: 19181.7
Deduct 154 from 170 and we're left 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 8:
When dividing 160 by 22, we get 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 19181.77
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.

Our division results in 19181.77 with a remaining 0.006.
