We look at the division of 90465948 by 42 
We want to divide 90465948 by 42.

Going ahead to step 1:
The number 42 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 42

Let's proceed to step 2:
90 divided by 42 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 6 after subtracting 84 from 90.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 42

Step 3:
The number 42 fits into 64 1 times, leaving a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 42 away from 64, we end up with 22.
Append the next digit (6) from the dividend to 22 and continue with: 226 / 42

On to step 4:
226 divided by 42 is 5 with a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 215.0
The remainder is 16 after subtracting 210 from 226.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 42

Moving on to step 5:
When dividing 165 by 42, we get 3 with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 2153.0
The remainder is 39 after subtracting 126 from 165.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 42

Going ahead to step 6:
The number 42 fits into 399 9 times, leaving a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 21539.0
Subtracting 378 from 399 leaves us with 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 42

Let's proceed to step 7:
214 divided by 42 is 5 with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 215395.0
If we subtract 210 from 214, we get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 42

Let's proceed to step 8:
48 divided by 42 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 2153951.0
If we take 42 away from 48, 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.

On to step 9:
60 divided by 42 is 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 2153951.1
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 2153951.14
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
120 divided by 42 is 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 2153951.142
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
The number 42 fits into 360 8 times, leaving a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 2153951.1428
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 2153951.14285
If we take 210 away from 240, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
42 goes into 300 7 times with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 2153951.142857
Deduct 294 from 300 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.

Advancing to step 15:
42 can be fit into 60 1 times, resulting in a remainder of 18.
The next digit of our result is 1. 
Result so far: 2153951.1428571
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 16:
When dividing 180 by 42, we get 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 2153951.14285714
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 2153951.14285714 and a remainder of 1.2e-08.
