We look at the division of 90344639 by 353 
We want to divide 90344639 by 353.

Moving on to step 1:
When dividing 9 by 353, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 353

Step 2:
If we divide 90 by 353, we get 0 and a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Take the next digit (3) from the dividend and append it to 90, then repeat: 903 / 353

Going ahead to step 3:
353 can be fit into 903 2 times, resulting in a remainder of 197.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 706 from 903 leaves us with 197.
Grab the next digit (4) from the dividend, add it to 197, then carry on: 1974 / 353

Going ahead to step 4:
1974 divided by 353 is 5 with a remainder of 209.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtract 1765 from 1974 to get 209.
Bring next digit (4) of the dividend behind the 209 and repeat the process: 2094 / 353

On to step 5:
If we divide 2094 by 353, we get 5 and a remainder of 329.
Use 5 as the next digit of our solution. 
Result so far: 255.0
Deduct 1765 from 2094 and we're left with 329.
Fetch the next digit (6) from the dividend, attach it to 329 and continue: 3296 / 353

Moving on to step 6:
353 goes into 3296 9 times with a remainder of 119.
Record the quotient 9 as the next digit in the result. 
Result so far: 2559.0
The remainder is 119 after subtracting 3177 from 3296.
Append the next digit (3) from the dividend to 119 and continue with: 1193 / 353

Moving on to step 7:
The number 353 fits into 1193 3 times, leaving a remainder of 134.
Record the quotient 3 as the next digit in the result. 
Result so far: 25593.0
If we take 1059 away from 1193, we end up with 134.
Bring next digit (9) of the dividend behind the 134 and repeat the process: 1349 / 353

Moving on to step 8:
If we divide 1349 by 353, we get 3 and a remainder of 290.
Use 3 as the next digit of our solution. 
Result so far: 255933.0
Subtract 1059 from 1349 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 9:
353 goes into 2900 8 times with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 255933.8
Subtracting 2824 from 2900 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
760 divided by 353 is 2 with a remainder of 54.
The next digit of our result is 2. 
Result so far: 255933.82
The remainder is 54 after subtracting 706 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 11:
540 divided by 353 is 1 with a remainder of 187.
Use 1 as the next digit of our solution. 
Result so far: 255933.821
The remainder is 187 after subtracting 353 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 12:
1870 divided by 353 is 5 with a remainder of 105.
Write down 5 as next digit of the result. 
Result so far: 255933.8215
Deduct 1765 from 1870 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 13:
353 can be fit into 1050 2 times, resulting in a remainder of 344.
Use 2 as the next digit of our solution. 
Result so far: 255933.82152
The remainder is 344 after subtracting 706 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 14:
3440 divided by 353 is 9 with a remainder of 263.
Put 9 as the next digit of the answer. 
Result so far: 255933.821529
Deduct 3177 from 3440 and we're left with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Moving on to step 15:
The number 353 fits into 2630 7 times, leaving a remainder of 159.
The number 7 becomes the next digit in our result. 
Result so far: 255933.8215297
Subtract 2471 from 2630 to get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Step 16:
When dividing 1590 by 353, we get 4 with a remainder of 178.
Write down 4 as next digit of the result. 
Result so far: 255933.82152974
Deduct 1412 from 1590 and we're left with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

The quotient of the division is 255933.82152974, and the remainder is 1.78e-07.
