We look at the division of 902610 by 77 
We want to figure out the number of times 902610 can be divided by 77.

On to step 1:
If we divide 9 by 77, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 77

Let's proceed to step 2:
The number 77 fits into 90 1 times, leaving a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 77 from 90 leaves us with 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 77

On to step 3:
The number 77 fits into 132 1 times, leaving a remainder of 55.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 77 from 132 leaves us with 55.
Bring next digit (6) of the dividend behind the 55 and repeat the process: 556 / 77

Going ahead to step 4:
77 goes into 556 7 times with a remainder of 17.
The next digit of our result is 7. 
Result so far: 117.0
Deduct 539 from 556 and we're left with 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 77

Going ahead to step 5:
77 can be fit into 171 2 times, resulting in a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 1172.0
Subtracting 154 from 171 leaves us with 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 77

Going ahead to step 6:
When dividing 170 by 77, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 11722.0
Subtracting 154 from 170 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
If we divide 160 by 77, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 11722.2
If we take 154 away from 160, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
77 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 11722.2
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
The number 77 fits into 600 7 times, leaving a remainder of 61.
Write down 7 as next digit of the result. 
Result so far: 11722.207
If we subtract 539 from 600, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 10:
610 divided by 77 is 7 with a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 11722.2077
Subtracting 539 from 610 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

After the division, we end up with 11722.2077 and a remainder of 0.00071.
