42120102 divided by 22 
We want to divide 42120102 by 22.

Advancing to step 1:
22 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 22

Moving on to step 2:
22 can be fit into 42 1 times, resulting in a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 22 from 42 leaves us with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 22

Advancing to step 3:
The number 22 fits into 201 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 198 from 201 and we're left with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 22

Step 4:
22 can be fit into 32 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 191.0
Subtracting 22 from 32 leaves us with 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 22

Advancing to step 5:
22 goes into 100 4 times with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 1914.0
If we take 88 away from 100, we end up with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 22

Moving on to step 6:
22 goes into 121 5 times with a remainder of 11.
The next digit of our result is 5. 
Result so far: 19145.0
Subtracting 110 from 121 leaves us with 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 22

Going ahead to step 7:
22 can be fit into 110 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 191455.0
Subtracting 110 from 110 leaves us with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 22

On to step 8:
22 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 1914550.0
The remainder is 2 after subtracting 0 from 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
When dividing 20 by 22, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1914550.0
Subtracting 0 from 20 leaves us 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.

Advancing to step 10:
When dividing 200 by 22, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 1914550.09
Deduct 198 from 200 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 11:
20 divided by 22 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1914550.09
Subtracting 0 from 20 leaves us 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.

Step 12:
22 can be fit into 200 9 times, resulting in a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 1914550.0909
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
The number 22 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1914550.0909
Deduct 0 from 20 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.

On to step 14:
22 goes into 200 9 times with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 1914550.090909
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 15:
22 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1914550.090909
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 16:
If we divide 200 by 22, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 1914550.09090909
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 1914550.09090909 and a remainder of 2e-09.
