We look at the division of 900638 by 42 
Let's see how many times 42 fits into 900638.

Let's proceed to step 1:
The number 42 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 42

Step 2:
When dividing 90 by 42, we get 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 84 from 90 and we're left with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 42

Moving on to step 3:
When dividing 60 by 42, we get 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 42 from 60 and we're left with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 42

Moving on to step 4:
If we divide 186 by 42, we get 4 and a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 214.0
Subtracting 168 from 186 leaves us with 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 42

Let's proceed to step 5:
The number 42 fits into 183 4 times, leaving a remainder of 15.
The next digit of our result is 4. 
Result so far: 2144.0
Subtracting 168 from 183 leaves us with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 42

Going ahead to step 6:
If we divide 158 by 42, we get 3 and a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 21443.0
Subtracting 126 from 158 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 7:
42 goes into 320 7 times with a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 21443.7
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
When dividing 260 by 42, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 21443.76
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
80 divided by 42 is 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 21443.761
Deduct 42 from 80 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 10:
380 divided by 42 is 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 21443.7619
Subtracting 378 from 380 leaves us 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.

Step 11:
42 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 21443.7619
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
200 divided by 42 is 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 21443.761904
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
42 goes into 320 7 times with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 21443.7619047
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
When dividing 260 by 42, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 21443.76190476
Subtract 252 from 260 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 21443.76190476 with a remaining 8e-09.
