86982674 divided by 77 
Our goal is to divide 86982674 by 77.

Advancing to step 1:
8 divided by 77 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 77

Let's proceed to step 2:
When dividing 86 by 77, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 77 away from 86, we end up with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 77

Moving on to step 3:
When dividing 99 by 77, we get 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 77 from 99, we get 22.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 77

Moving on to step 4:
77 can be fit into 228 2 times, resulting in a remainder of 74.
The next digit of our result is 2. 
Result so far: 112.0
Subtracting 154 from 228 leaves us with 74.
Fetch the next digit (2) from the dividend, attach it to 74 and continue: 742 / 77

Moving on to step 5:
77 can be fit into 742 9 times, resulting in a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 1129.0
Deduct 693 from 742 and we're left with 49.
Append the next digit (6) from the dividend to 49 and continue with: 496 / 77

On to step 6:
The number 77 fits into 496 6 times, leaving a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 11296.0
Subtracting 462 from 496 leaves us with 34.
Include the next digit (7) from the dividend after 34, then repeat: 347 / 77

Moving on to step 7:
347 divided by 77 is 4 with a remainder of 39.
The next digit of our result is 4. 
Result so far: 112964.0
The remainder is 39 after subtracting 308 from 347.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 77

Going ahead to step 8:
77 can be fit into 394 5 times, resulting in a remainder of 9.
The next digit of our result is 5. 
Result so far: 1129645.0
Subtract 385 from 394 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
If we divide 90 by 77, we get 1 and a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1129645.1
Subtracting 77 from 90 leaves us 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 10:
77 goes into 130 1 times with a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 1129645.11
The remainder is 53 after subtracting 77 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The final result is 1129645.11 with a remainder of 0.053.
