17688980 ÷ 913 
We want to figure out the number of times 17688980 can be divided by 913.

On to step 1:
1 divided by 913 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 913

On to step 2:
If we divide 17 by 913, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 913

On to step 3:
If we divide 176 by 913, we get 0 and a remainder of 176.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 176 to get 176.
Fetch the next digit (8) from the dividend, attach it to 176 and continue: 1768 / 913

Let's proceed to step 4:
913 goes into 1768 1 times with a remainder of 855.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 913 from 1768 and we're left with 855.
Fetch the next digit (8) from the dividend, attach it to 855 and continue: 8558 / 913

On to step 5:
913 goes into 8558 9 times with a remainder of 341.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 8217 from 8558 and we're left with 341.
Bring next digit (9) of the dividend behind the 341 and repeat the process: 3419 / 913

Going ahead to step 6:
913 can be fit into 3419 3 times, resulting in a remainder of 680.
Use 3 as the next digit of our solution. 
Result so far: 193.0
If we take 2739 away from 3419, we end up with 680.
Fetch the next digit (8) from the dividend, attach it to 680 and continue: 6808 / 913

Moving on to step 7:
6808 divided by 913 is 7 with a remainder of 417.
The next digit of our result is 7. 
Result so far: 1937.0
If we subtract 6391 from 6808, we get 417.
Include the next digit (0) from the dividend after 417, then repeat: 4170 / 913

Advancing to step 8:
When dividing 4170 by 913, we get 4 with a remainder of 518.
The number 4 becomes the next digit in our result. 
Result so far: 19374.0
The remainder is 518 after subtracting 3652 from 4170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

On to step 9:
If we divide 5180 by 913, we get 5 and a remainder of 615.
The next digit of our result is 5. 
Result so far: 19374.5
Deduct 4565 from 5180 and we're left with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Moving on to step 10:
913 can be fit into 6150 6 times, resulting in a remainder of 672.
Use 6 as the next digit of our solution. 
Result so far: 19374.56
The remainder is 672 after subtracting 5478 from 6150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

On to step 11:
If we divide 6720 by 913, we get 7 and a remainder of 329.
Put 7 as the next digit of the answer. 
Result so far: 19374.567
If we take 6391 away from 6720, we end up with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

On to step 12:
913 can be fit into 3290 3 times, resulting in a remainder of 551.
The next digit of our result is 3. 
Result so far: 19374.5673
Subtract 2739 from 3290 to get 551.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Step 13:
When dividing 5510 by 913, we get 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 19374.56736
Deduct 5478 from 5510 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
320 divided by 913 is 0 with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 19374.56736
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 15:
When dividing 3200 by 913, we get 3 with a remainder of 461.
Record the quotient 3 as the next digit in the result. 
Result so far: 19374.5673603
Deduct 2739 from 3200 and we're left with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Let's proceed to step 16:
4610 divided by 913 is 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 19374.56736035
If we take 4565 away from 4610, we end up with 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 outcome is 19374.56736035, with a leftover of 4.5e-08.
