84239111 ÷ 677 
We want to figure out the number of times 84239111 can be divided by 677.

On to step 1:
8 divided by 677 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 677

Let's proceed to step 2:
677 can be fit into 84 0 times, resulting in a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Take the next digit (2) from the dividend and append it to 84, then repeat: 842 / 677

Let's proceed to step 3:
If we divide 842 by 677, we get 1 and a remainder of 165.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 677 from 842, we get 165.
Grab the next digit (3) from the dividend, add it to 165, then carry on: 1653 / 677

Advancing to step 4:
The number 677 fits into 1653 2 times, leaving a remainder of 299.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 1354 from 1653 and we're left with 299.
Include the next digit (9) from the dividend after 299, then repeat: 2999 / 677

Advancing to step 5:
2999 divided by 677 is 4 with a remainder of 291.
Use 4 as the next digit of our solution. 
Result so far: 124.0
The remainder is 291 after subtracting 2708 from 2999.
Append the next digit (1) from the dividend to 291 and continue with: 2911 / 677

Step 6:
2911 divided by 677 is 4 with a remainder of 203.
Record the quotient 4 as the next digit in the result. 
Result so far: 1244.0
Subtracting 2708 from 2911 leaves us with 203.
Fetch the next digit (1) from the dividend, attach it to 203 and continue: 2031 / 677

Let's proceed to step 7:
2031 divided by 677 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 12443.0
If we take 2031 away from 2031, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 677

Advancing to step 8:
If we divide 1 by 677, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 124430.0
Subtract 0 from 1 to get 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:
10 divided by 677 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 124430.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
100 divided by 677 is 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 124430.0
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 124430.0, with a leftover of 0.1.
