86498567 ÷ 77 
Our goal is to divide 86498567 by 77.

Going ahead to step 1:
If we divide 8 by 77, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 77

Step 2:
When dividing 86 by 77, we get 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 9 after subtracting 77 from 86.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 77

Step 3:
77 goes into 94 1 times with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 77 from 94 to get 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 77

Moving on to step 4:
When dividing 179 by 77, we get 2 with a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
The remainder is 25 after subtracting 154 from 179.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 77

Advancing to step 5:
If we divide 258 by 77, we get 3 and a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 1123.0
Subtracting 231 from 258 leaves us with 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 77

Advancing to step 6:
275 divided by 77 is 3 with a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 11233.0
Subtract 231 from 275 to get 44.
Bring next digit (6) of the dividend behind the 44 and repeat the process: 446 / 77

Let's proceed to step 7:
77 goes into 446 5 times with a remainder of 61.
Use 5 as the next digit of our solution. 
Result so far: 112335.0
Deduct 385 from 446 and we're left with 61.
Bring next digit (7) of the dividend behind the 61 and repeat the process: 617 / 77

Moving on to step 8:
77 can be fit into 617 8 times, resulting in a remainder of 1.
The next digit of our result is 8. 
Result so far: 1123358.0
Deduct 616 from 617 and we're left 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.

Step 9:
The number 77 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1123358.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
If we divide 100 by 77, we get 1 and a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1123358.01
If we take 77 away from 100, we end up 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.

Advancing to step 11:
The number 77 fits into 230 2 times, leaving a remainder of 76.
The next digit of our result is 2. 
Result so far: 1123358.012
Subtract 154 from 230 to 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.

Going ahead to step 12:
77 can be fit into 760 9 times, resulting in a remainder of 67.
The next digit of our result is 9. 
Result so far: 1123358.0129
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.

Moving on to step 13:
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: 1123358.01298
The remainder is 54 after subtracting 616 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 14:
The number 77 fits into 540 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 1123358.012987
Subtracting 539 from 540 leaves us 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.

Going ahead to step 15:
10 divided by 77 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 1123358.012987
If we take 0 away from 10, we end up 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.

Advancing to step 16:
77 can be fit into 100 1 times, resulting in a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1123358.01298701
If we take 77 away from 100, we end up 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.

The final outcome is 1123358.01298701, with a leftover of 2.3e-08.
