We divide 86660904 by 353
We want to figure out the number of times 86660904 can be divided by 353.

Going ahead to step 1:
353 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 353

Going ahead to step 2:
353 can be fit into 86 0 times, resulting in a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Fetch the next digit (6) from the dividend, attach it to 86 and continue: 866 / 353

Advancing to step 3:
353 can be fit into 866 2 times, resulting in a remainder of 160.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 706 away from 866, we end up with 160.
Take the next digit (6) from the dividend and append it to 160, then repeat: 1606 / 353

On to step 4:
353 goes into 1606 4 times with a remainder of 194.
The next digit of our result is 4. 
Result so far: 24.0
If we subtract 1412 from 1606, we get 194.
Take the next digit (0) from the dividend and append it to 194, then repeat: 1940 / 353

Advancing to step 5:
353 goes into 1940 5 times with a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 245.0
If we subtract 1765 from 1940, we get 175.
Include the next digit (9) from the dividend after 175, then repeat: 1759 / 353

Advancing to step 6:
353 can be fit into 1759 4 times, resulting in a remainder of 347.
Record the quotient 4 as the next digit in the result. 
Result so far: 2454.0
The remainder is 347 after subtracting 1412 from 1759.
Append the next digit (0) from the dividend to 347 and continue with: 3470 / 353

On to step 7:
When dividing 3470 by 353, we get 9 with a remainder of 293.
The next digit of our result is 9. 
Result so far: 24549.0
Subtracting 3177 from 3470 leaves us with 293.
Include the next digit (4) from the dividend after 293, then repeat: 2934 / 353

On to step 8:
353 goes into 2934 8 times with a remainder of 110.
Record the quotient 8 as the next digit in the result. 
Result so far: 245498.0
If we take 2824 away from 2934, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 9:
When dividing 1100 by 353, we get 3 with a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 245498.3
If we subtract 1059 from 1100, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 10:
410 divided by 353 is 1 with a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 245498.31
If we subtract 353 from 410, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 11:
570 divided by 353 is 1 with a remainder of 217.
Write down 1 as next digit of the result. 
Result so far: 245498.311
Subtract 353 from 570 to get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Our division results in 245498.311 with a remaining 0.0217.
