We divide 87177020 by 77
We want to figure out the number of times 87177020 can be divided by 77.

Going ahead to step 1:
77 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 77

Advancing to step 2:
The number 77 fits into 87 1 times, leaving a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 77 from 87 and we're left with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 77

Let's proceed to step 3:
When dividing 101 by 77, we get 1 with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 77 from 101, we get 24.
Take the next digit (7) from the dividend and append it to 24, then repeat: 247 / 77

Going ahead to step 4:
If we divide 247 by 77, we get 3 and a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
Deduct 231 from 247 and we're left with 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 77

Moving on to step 5:
The number 77 fits into 167 2 times, leaving a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 1132.0
The remainder is 13 after subtracting 154 from 167.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 77

Advancing to step 6:
77 goes into 130 1 times with a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 11321.0
The remainder is 53 after subtracting 77 from 130.
Bring next digit (2) of the dividend behind the 53 and repeat the process: 532 / 77

Let's proceed to step 7:
The number 77 fits into 532 6 times, leaving a remainder of 70.
Record the quotient 6 as the next digit in the result. 
Result so far: 113216.0
Deduct 462 from 532 and we're left with 70.
Take the next digit (0) from the dividend and append it to 70, then repeat: 700 / 77

Going ahead to step 8:
77 goes into 700 9 times with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 1132169.0
Deduct 693 from 700 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
If we divide 70 by 77, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 1132169.0
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
700 divided by 77 is 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 1132169.09
The remainder is 7 after subtracting 693 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 11:
If we divide 70 by 77, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 1132169.09
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 12:
When dividing 700 by 77, we get 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 1132169.0909
The remainder is 7 after subtracting 693 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 13:
If we divide 70 by 77, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 1132169.0909
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 14:
If we divide 700 by 77, we get 9 and a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 1132169.090909
If we take 693 away from 700, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 15:
77 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 1132169.090909
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 16:
When dividing 700 by 77, we get 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 1132169.09090909
If we take 693 away from 700, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 1132169.09090909, and the remainder is 7e-09.
