902221 ÷ 55 
We're looking to find how many times 55 goes into 902221.

Step 1:
When dividing 9 by 55, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 55

On to step 2:
55 can be fit into 90 1 times, resulting in a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 55 from 90 to get 35.
Fetch the next digit (2) from the dividend, attach it to 35 and continue: 352 / 55

Advancing to step 3:
If we divide 352 by 55, we get 6 and a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 330 from 352 leaves us with 22.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 55

Let's proceed to step 4:
55 goes into 222 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 164.0
Deduct 220 from 222 and we're left with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 55

Advancing to step 5:
The number 55 fits into 22 0 times, leaving a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 1640.0
If we take 0 away from 22, we end up with 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 55

Going ahead to step 6:
221 divided by 55 is 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 16404.0
If we take 220 away from 221, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
55 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 16404.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 55, we get 1 with a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 16404.01
The remainder is 45 after subtracting 55 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 9:
If we divide 450 by 55, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 16404.018
Deduct 440 from 450 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
55 can be fit into 100 1 times, resulting in a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 16404.0181
Subtract 55 from 100 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 11:
When dividing 450 by 55, we get 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 16404.01818
Subtract 440 from 450 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
55 can be fit into 100 1 times, resulting in a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 16404.018181
If we subtract 55 from 100, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 13:
450 divided by 55 is 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 16404.0181818
The remainder is 10 after subtracting 440 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
The number 55 fits into 100 1 times, leaving a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 16404.01818181
Subtract 55 from 100 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 16404.01818181 with a remainder of 4.5e-08.
