We're dividing 90084221 by 353 
We want to figure out the number of times 90084221 can be divided by 353.

Moving on to step 1:
If we divide 9 by 353, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 353

On to step 2:
353 goes into 90 0 times with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Fetch the next digit (0) from the dividend, attach it to 90 and continue: 900 / 353

Let's proceed to step 3:
If we divide 900 by 353, we get 2 and a remainder of 194.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 706 from 900 and we're left with 194.
Take the next digit (8) from the dividend and append it to 194, then repeat: 1948 / 353

Step 4:
The number 353 fits into 1948 5 times, leaving a remainder of 183.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtract 1765 from 1948 to get 183.
Fetch the next digit (4) from the dividend, attach it to 183 and continue: 1834 / 353

Moving on to step 5:
353 can be fit into 1834 5 times, resulting in a remainder of 69.
Use 5 as the next digit of our solution. 
Result so far: 255.0
Deduct 1765 from 1834 and we're left with 69.
Fetch the next digit (2) from the dividend, attach it to 69 and continue: 692 / 353

Going ahead to step 6:
353 can be fit into 692 1 times, resulting in a remainder of 339.
Use 1 as the next digit of our solution. 
Result so far: 2551.0
Subtract 353 from 692 to get 339.
Bring next digit (2) of the dividend behind the 339 and repeat the process: 3392 / 353

Let's proceed to step 7:
The number 353 fits into 3392 9 times, leaving a remainder of 215.
The next digit of our result is 9. 
Result so far: 25519.0
If we take 3177 away from 3392, we end up with 215.
Bring next digit (1) of the dividend behind the 215 and repeat the process: 2151 / 353

Advancing to step 8:
353 goes into 2151 6 times with a remainder of 33.
Put 6 as the next digit of the answer. 
Result so far: 255196.0
If we take 2118 away from 2151, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 9:
353 can be fit into 330 0 times, resulting in a remainder of 330.
Use 0 as the next digit of our solution. 
Result so far: 255196.0
Deduct 0 from 330 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 10:
If we divide 3300 by 353, we get 9 and a remainder of 123.
Record the quotient 9 as the next digit in the result. 
Result so far: 255196.09
Subtract 3177 from 3300 to get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 11:
The number 353 fits into 1230 3 times, leaving a remainder of 171.
The next digit of our result is 3. 
Result so far: 255196.093
If we take 1059 away from 1230, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Going ahead to step 12:
353 can be fit into 1710 4 times, resulting in a remainder of 298.
Write down 4 as next digit of the result. 
Result so far: 255196.0934
Subtract 1412 from 1710 to get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Step 13:
2980 divided by 353 is 8 with a remainder of 156.
Use 8 as the next digit of our solution. 
Result so far: 255196.09348
If we take 2824 away from 2980, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 14:
When dividing 1560 by 353, we get 4 with a remainder of 148.
Use 4 as the next digit of our solution. 
Result so far: 255196.093484
If we subtract 1412 from 1560, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 15:
353 can be fit into 1480 4 times, resulting in a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 255196.0934844
Subtract 1412 from 1480 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final outcome is 255196.0934844, with a leftover of 6.8e-07.
