We look at the division of 691079 by 90 
Let's see how many times 90 fits into 691079.

Let's proceed to step 1:
When dividing 6 by 90, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 90

Advancing to step 2:
69 divided by 90 is 0 with a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Fetch the next digit (1) from the dividend, attach it to 69 and continue: 691 / 90

Let's proceed to step 3:
90 goes into 691 7 times with a remainder of 61.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 630 from 691 leaves us with 61.
Grab the next digit (0) from the dividend, add it to 61, then carry on: 610 / 90

Going ahead to step 4:
The number 90 fits into 610 6 times, leaving a remainder of 70.
Put 6 as the next digit of the answer. 
Result so far: 76.0
If we take 540 away from 610, we end up with 70.
Take the next digit (7) from the dividend and append it to 70, then repeat: 707 / 90

Step 5:
90 goes into 707 7 times with a remainder of 77.
Put 7 as the next digit of the answer. 
Result so far: 767.0
If we take 630 away from 707, we end up with 77.
Take the next digit (9) from the dividend and append it to 77, then repeat: 779 / 90

Advancing to step 6:
90 can be fit into 779 8 times, resulting in a remainder of 59.
Put 8 as the next digit of the answer. 
Result so far: 7678.0
If we take 720 away from 779, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 7:
If we divide 590 by 90, we get 6 and a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 7678.6
Deduct 540 from 590 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 7678.65
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 7678.655
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 7678.655 with a remaining 0.005.
