We divide 97171777 by 77
Our goal is to divide 97171777 by 77.

On to step 1:
77 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the 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

On to step 2:
When dividing 97 by 77, we get 1 with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 77 from 97 and we're left with 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 77

On to step 3:
201 divided by 77 is 2 with a remainder of 47.
The next digit of our result is 2. 
Result so far: 12.0
If we take 154 away from 201, we end up with 47.
Take the next digit (7) from the dividend and append it to 47, then repeat: 477 / 77

Advancing to step 4:
If we divide 477 by 77, we get 6 and a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 126.0
If we take 462 away from 477, we end up with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 77

Going ahead to step 5:
If we divide 151 by 77, we get 1 and a remainder of 74.
Write down 1 as next digit of the result. 
Result so far: 1261.0
Subtract 77 from 151 to get 74.
Take the next digit (7) from the dividend and append it to 74, then repeat: 747 / 77

Step 6:
77 goes into 747 9 times with a remainder of 54.
Put 9 as the next digit of the answer. 
Result so far: 12619.0
Subtract 693 from 747 to get 54.
Take the next digit (7) from the dividend and append it to 54, then repeat: 547 / 77

Let's proceed to step 7:
When dividing 547 by 77, we get 7 with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 126197.0
Deduct 539 from 547 and we're left with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 77

Step 8:
77 goes into 87 1 times with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1261971.0
Subtracting 77 from 87 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
100 divided by 77 is 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1261971.1
Subtracting 77 from 100 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 10:
77 goes into 230 2 times with a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 1261971.12
Deduct 154 from 230 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 11:
760 divided by 77 is 9 with a remainder of 67.
The next digit of our result is 9. 
Result so far: 1261971.129
If we take 693 away from 760, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 12:
If we divide 670 by 77, we get 8 and a remainder of 54.
The next digit of our result is 8. 
Result so far: 1261971.1298
If we subtract 616 from 670, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 13:
The number 77 fits into 540 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 1261971.12987
If we take 539 away from 540, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
The number 77 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1261971.12987
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 15:
When dividing 100 by 77, we get 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1261971.1298701
Subtract 77 from 100 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 16:
If we divide 230 by 77, we get 2 and a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 1261971.12987012
If we subtract 154 from 230, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 1261971.12987012 and a remainder of 7.6e-08.
