84135923 ÷ 791 
Our goal is to divide 84135923 by 791.

Going ahead to step 1:
When dividing 8 by 791, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 791

Moving on to step 2:
791 goes into 84 0 times with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Include the next digit (1) from the dividend after 84, then repeat: 841 / 791

Going ahead to step 3:
791 can be fit into 841 1 times, resulting in a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 50 after subtracting 791 from 841.
Include the next digit (3) from the dividend after 50, then repeat: 503 / 791

Going ahead to step 4:
791 goes into 503 0 times with a remainder of 503.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 503, we end up with 503.
Grab the next digit (5) from the dividend, add it to 503, then carry on: 5035 / 791

On to step 5:
5035 divided by 791 is 6 with a remainder of 289.
Put 6 as the next digit of the answer. 
Result so far: 106.0
The remainder is 289 after subtracting 4746 from 5035.
Include the next digit (9) from the dividend after 289, then repeat: 2899 / 791

Moving on to step 6:
791 can be fit into 2899 3 times, resulting in a remainder of 526.
Record the quotient 3 as the next digit in the result. 
Result so far: 1063.0
If we subtract 2373 from 2899, we get 526.
Append the next digit (2) from the dividend to 526 and continue with: 5262 / 791

Going ahead to step 7:
791 goes into 5262 6 times with a remainder of 516.
Use 6 as the next digit of our solution. 
Result so far: 10636.0
Deduct 4746 from 5262 and we're left with 516.
Grab the next digit (3) from the dividend, add it to 516, then carry on: 5163 / 791

Step 8:
5163 divided by 791 is 6 with a remainder of 417.
The number 6 becomes the next digit in our result. 
Result so far: 106366.0
Deduct 4746 from 5163 and we're left with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Let's proceed to step 9:
791 can be fit into 4170 5 times, resulting in a remainder of 215.
The next digit of our result is 5. 
Result so far: 106366.5
Subtract 3955 from 4170 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 10:
2150 divided by 791 is 2 with a remainder of 568.
The number 2 becomes the next digit in our result. 
Result so far: 106366.52
Subtracting 1582 from 2150 leaves us with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

On to step 11:
The number 791 fits into 5680 7 times, leaving a remainder of 143.
Use 7 as the next digit of our solution. 
Result so far: 106366.527
Subtract 5537 from 5680 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Step 12:
791 can be fit into 1430 1 times, resulting in a remainder of 639.
Use 1 as the next digit of our solution. 
Result so far: 106366.5271
The remainder is 639 after subtracting 791 from 1430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Step 13:
When dividing 6390 by 791, we get 8 with a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 106366.52718
Deduct 6328 from 6390 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 14:
When dividing 620 by 791, we get 0 with a remainder of 620.
Write down 0 as next digit of the result. 
Result so far: 106366.52718
If we subtract 0 from 620, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 15:
The number 791 fits into 6200 7 times, leaving a remainder of 663.
The next digit of our result is 7. 
Result so far: 106366.5271807
The remainder is 663 after subtracting 5537 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Step 16:
The number 791 fits into 6630 8 times, leaving a remainder of 302.
Use 8 as the next digit of our solution. 
Result so far: 106366.52718078
Deduct 6328 from 6630 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

After the division, we end up with 106366.52718078 and a remainder of 3.02e-07.
