We divide 972519 by 77
We want to divide 972519 by 77.

On to step 1:
If we divide 9 by 77, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 77

Let's proceed to step 2:
When dividing 97 by 77, we get 1 with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 77 from 97 leaves us with 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 77

On to step 3:
77 goes into 202 2 times with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 154 away from 202, we end up with 48.
Include the next digit (5) from the dividend after 48, then repeat: 485 / 77

Advancing to step 4:
485 divided by 77 is 6 with a remainder of 23.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
Subtracting 462 from 485 leaves us with 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 77

Let's proceed to step 5:
If we divide 231 by 77, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 1263.0
Deduct 231 from 231 and we're left with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 77

Advancing to step 6:
If we divide 9 by 77, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 12630.0
If we take 0 away from 9, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
If we divide 90 by 77, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 12630.1
Deduct 77 from 90 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 8:
When dividing 130 by 77, we get 1 with a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 12630.11
If we take 77 away from 130, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

After the division, we end up with 12630.11 and a remainder of 0.053.
