We look at the division of 17093930 by 686 
We want to figure out the number of times 17093930 can be divided by 686.

Advancing to step 1:
The number 686 fits into 1 0 times, leaving 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.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 686

On to step 2:
If we divide 17 by 686, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 686

Moving on to step 3:
170 divided by 686 is 0 with a remainder of 170.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 170, we end up with 170.
Include the next digit (9) from the dividend after 170, then repeat: 1709 / 686

Let's proceed to step 4:
If we divide 1709 by 686, we get 2 and a remainder of 337.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1372 from 1709 leaves us with 337.
Include the next digit (3) from the dividend after 337, then repeat: 3373 / 686

On to step 5:
3373 divided by 686 is 4 with a remainder of 629.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Deduct 2744 from 3373 and we're left with 629.
Fetch the next digit (9) from the dividend, attach it to 629 and continue: 6299 / 686

Going ahead to step 6:
686 goes into 6299 9 times with a remainder of 125.
Record the quotient 9 as the next digit in the result. 
Result so far: 249.0
Deduct 6174 from 6299 and we're left with 125.
Fetch the next digit (3) from the dividend, attach it to 125 and continue: 1253 / 686

Let's proceed to step 7:
When dividing 1253 by 686, we get 1 with a remainder of 567.
The number 1 becomes the next digit in our result. 
Result so far: 2491.0
Subtracting 686 from 1253 leaves us with 567.
Append the next digit (0) from the dividend to 567 and continue with: 5670 / 686

Let's proceed to step 8:
When dividing 5670 by 686, we get 8 with a remainder of 182.
The next digit of our result is 8. 
Result so far: 24918.0
The remainder is 182 after subtracting 5488 from 5670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Going ahead to step 9:
686 can be fit into 1820 2 times, resulting in a remainder of 448.
Put 2 as the next digit of the answer. 
Result so far: 24918.2
Subtract 1372 from 1820 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 10:
4480 divided by 686 is 6 with a remainder of 364.
Record the quotient 6 as the next digit in the result. 
Result so far: 24918.26
Subtract 4116 from 4480 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 11:
When dividing 3640 by 686, we get 5 with a remainder of 210.
Put 5 as the next digit of the answer. 
Result so far: 24918.265
If we subtract 3430 from 3640, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 12:
686 goes into 2100 3 times with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 24918.2653
If we take 2058 away from 2100, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
686 can be fit into 420 0 times, resulting in a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 24918.2653
If we subtract 0 from 420, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 14:
686 can be fit into 4200 6 times, resulting in a remainder of 84.
The next digit of our result is 6. 
Result so far: 24918.265306
If we take 4116 away from 4200, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 15:
When dividing 840 by 686, we get 1 with a remainder of 154.
Put 1 as the next digit of the answer. 
Result so far: 24918.2653061
Deduct 686 from 840 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 16:
When dividing 1540 by 686, we get 2 with a remainder of 168.
The number 2 becomes the next digit in our result. 
Result so far: 24918.26530612
Deduct 1372 from 1540 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

In conclusion, the division gives 24918.26530612 with a balance of 1.68e-07.
