Let's divide 688758 by 7
We want to figure out the number of times 688758 can be divided by 7.

On to step 1:
6 divided by 7 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 7

Going ahead to step 2:
If we divide 68 by 7, we get 9 and a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 63 away from 68, we end up with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 7

Let's proceed to step 3:
58 divided by 7 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 98.0
Subtracting 56 from 58 leaves us with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 7

Going ahead to step 4:
If we divide 27 by 7, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 983.0
Subtracting 21 from 27 leaves us with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 7

Advancing to step 5:
7 goes into 65 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 9839.0
Subtract 63 from 65 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 7

On to step 6:
The number 7 fits into 28 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 98394.0
Deduct 28 from 28 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
7 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 98394.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
7 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 98394.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 98394.0 and a remainder of 0.0.
