We divide 42188405 by 42
Our goal is to divide 42188405 by 42.

Moving on to step 1:
When dividing 4 by 42, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 42

Step 2:
42 divided by 42 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 42 from 42, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 42

Advancing to step 3:
The number 42 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 42

Moving on to step 4:
When dividing 18 by 42, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Deduct 0 from 18 and we're left with 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 42

On to step 5:
If we divide 188 by 42, we get 4 and a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 1004.0
The remainder is 20 after subtracting 168 from 188.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 42

Moving on to step 6:
204 divided by 42 is 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 10044.0
Subtracting 168 from 204 leaves us with 36.
Bring next digit (0) of the dividend behind the 36 and repeat the process: 360 / 42

Moving on to step 7:
The number 42 fits into 360 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 100448.0
The remainder is 24 after subtracting 336 from 360.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 42

Going ahead to step 8:
When dividing 245 by 42, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 1004485.0
Deduct 210 from 245 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
When dividing 350 by 42, we get 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 1004485.8
If we take 336 away from 350, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
42 can be fit into 140 3 times, resulting in a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 1004485.83
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 11:
42 can be fit into 140 3 times, resulting in a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 1004485.833
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 1004485.833 and a remainder of 0.0014.
