77997147 divided by 83 
We want to figure out the number of times 77997147 can be divided by 83.

Step 1:
83 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 83

Step 2:
If we divide 77 by 83, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Fetch the next digit (9) from the dividend, attach it to 77 and continue: 779 / 83

On to step 3:
If we divide 779 by 83, we get 9 and a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 747 from 779 leaves us with 32.
Append the next digit (9) from the dividend to 32 and continue with: 329 / 83

Going ahead to step 4:
The number 83 fits into 329 3 times, leaving a remainder of 80.
Write down 3 as next digit of the result. 
Result so far: 93.0
If we take 249 away from 329, we end up with 80.
Take the next digit (7) from the dividend and append it to 80, then repeat: 807 / 83

Let's proceed to step 5:
The number 83 fits into 807 9 times, leaving a remainder of 60.
Use 9 as the next digit of our solution. 
Result so far: 939.0
Deduct 747 from 807 and we're left with 60.
Fetch the next digit (1) from the dividend, attach it to 60 and continue: 601 / 83

Moving on to step 6:
When dividing 601 by 83, we get 7 with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 9397.0
If we take 581 away from 601, we end up with 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 83

Going ahead to step 7:
If we divide 204 by 83, we get 2 and a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 93972.0
Subtracting 166 from 204 leaves us with 38.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 83

Let's proceed to step 8:
When dividing 387 by 83, we get 4 with a remainder of 55.
Record the quotient 4 as the next digit in the result. 
Result so far: 939724.0
Subtract 332 from 387 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 9:
When dividing 550 by 83, we get 6 with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 939724.6
The remainder is 52 after subtracting 498 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
The number 83 fits into 520 6 times, leaving a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 939724.66
Subtract 498 from 520 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 939724.66, with a leftover of 0.022.
