We divide 90222210 by 442
We want to divide 90222210 by 442.

Advancing to step 1:
9 divided by 442 is 0 with a remainder of 9.
The next digit of our result is 0. 
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 / 442

On to step 2:
442 can be fit into 90 0 times, resulting in a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Bring next digit (2) of the dividend behind the 90 and repeat the process: 902 / 442

Advancing to step 3:
The number 442 fits into 902 2 times, leaving a remainder of 18.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 18 after subtracting 884 from 902.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 442

Advancing to step 4:
If we divide 182 by 442, we get 0 and a remainder of 182.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtract 0 from 182 to get 182.
Bring next digit (2) of the dividend behind the 182 and repeat the process: 1822 / 442

On to step 5:
When dividing 1822 by 442, we get 4 with a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 204.0
The remainder is 54 after subtracting 1768 from 1822.
Include the next digit (2) from the dividend after 54, then repeat: 542 / 442

Moving on to step 6:
442 goes into 542 1 times with a remainder of 100.
The next digit of our result is 1. 
Result so far: 2041.0
Subtracting 442 from 542 leaves us with 100.
Take the next digit (1) from the dividend and append it to 100, then repeat: 1001 / 442

Going ahead to step 7:
442 goes into 1001 2 times with a remainder of 117.
Write down 2 as next digit of the result. 
Result so far: 20412.0
If we take 884 away from 1001, we end up with 117.
Bring next digit (0) of the dividend behind the 117 and repeat the process: 1170 / 442

On to step 8:
442 can be fit into 1170 2 times, resulting in a remainder of 286.
Write down 2 as next digit of the result. 
Result so far: 204122.0
If we subtract 884 from 1170, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Advancing to step 9:
442 can be fit into 2860 6 times, resulting in a remainder of 208.
Record the quotient 6 as the next digit in the result. 
Result so far: 204122.6
Subtracting 2652 from 2860 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 10:
The number 442 fits into 2080 4 times, leaving a remainder of 312.
Put 4 as the next digit of the answer. 
Result so far: 204122.64
If we take 1768 away from 2080, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 11:
If we divide 3120 by 442, we get 7 and a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 204122.647
Subtracting 3094 from 3120 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 12:
442 goes into 260 0 times with a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 204122.647
Subtract 0 from 260 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 13:
If we divide 2600 by 442, we get 5 and a remainder of 390.
Write down 5 as next digit of the result. 
Result so far: 204122.64705
Subtract 2210 from 2600 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 14:
If we divide 3900 by 442, we get 8 and a remainder of 364.
The next digit of our result is 8. 
Result so far: 204122.647058
If we take 3536 away from 3900, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 15:
When dividing 3640 by 442, we get 8 with a remainder of 104.
Use 8 as the next digit of our solution. 
Result so far: 204122.6470588
The remainder is 104 after subtracting 3536 from 3640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final result is 204122.6470588 with a remainder of 1.04e-06.
