86598 ÷ 77 
Let's see how many times 77 fits into 86598.

Let's proceed to step 1:
77 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 77

On to step 2:
If we divide 86 by 77, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 77 from 86 to get 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 77

Moving on to step 3:
77 can be fit into 95 1 times, resulting in a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 77 from 95 to get 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 77

Going ahead to step 4:
77 goes into 189 2 times with a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
Subtracting 154 from 189 leaves us with 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 77

Going ahead to step 5:
The number 77 fits into 358 4 times, leaving a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 1124.0
If we take 308 away from 358, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 6:
77 can be fit into 500 6 times, resulting in a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 1124.6
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
If we divide 380 by 77, we get 4 and a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 1124.64
If we take 308 away from 380, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 8:
When dividing 720 by 77, we get 9 with a remainder of 27.
The next digit of our result is 9. 
Result so far: 1124.649
If we subtract 693 from 720, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
77 can be fit into 270 3 times, resulting in a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 1124.6493
Subtracting 231 from 270 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 10:
If we divide 390 by 77, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 1124.64935
Deduct 385 from 390 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
If we divide 50 by 77, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 1124.64935
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
500 divided by 77 is 6 with a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 1124.6493506
Subtract 462 from 500 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 13:
The number 77 fits into 380 4 times, leaving a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 1124.64935064
Subtracting 308 from 380 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

In conclusion, the division gives 1124.64935064 with a balance of 7.2e-08.
