84038864 ÷ 830 
Our goal is to divide 84038864 by 830.

Step 1:
If we divide 8 by 830, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 830

Going ahead to step 2:
830 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
Deduct 0 from 84 and we're left with 84.
Append the next digit (0) from the dividend to 84 and continue with: 840 / 830

On to step 3:
830 goes into 840 1 times with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 830 from 840 to get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 830

Step 4:
830 can be fit into 103 0 times, resulting in a remainder of 103.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 103 to get 103.
Fetch the next digit (8) from the dividend, attach it to 103 and continue: 1038 / 830

Going ahead to step 5:
When dividing 1038 by 830, we get 1 with a remainder of 208.
The next digit of our result is 1. 
Result so far: 101.0
If we take 830 away from 1038, we end up with 208.
Grab the next digit (8) from the dividend, add it to 208, then carry on: 2088 / 830

Advancing to step 6:
The number 830 fits into 2088 2 times, leaving a remainder of 428.
Record the quotient 2 as the next digit in the result. 
Result so far: 1012.0
Deduct 1660 from 2088 and we're left with 428.
Bring next digit (6) of the dividend behind the 428 and repeat the process: 4286 / 830

Moving on to step 7:
830 can be fit into 4286 5 times, resulting in a remainder of 136.
Put 5 as the next digit of the answer. 
Result so far: 10125.0
If we take 4150 away from 4286, we end up with 136.
Take the next digit (4) from the dividend and append it to 136, then repeat: 1364 / 830

On to step 8:
The number 830 fits into 1364 1 times, leaving a remainder of 534.
Write down 1 as next digit of the result. 
Result so far: 101251.0
Deduct 830 from 1364 and we're left with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Step 9:
830 goes into 5340 6 times with a remainder of 360.
Put 6 as the next digit of the answer. 
Result so far: 101251.6
If we subtract 4980 from 5340, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 10:
830 goes into 3600 4 times with a remainder of 280.
Put 4 as the next digit of the answer. 
Result so far: 101251.64
If we subtract 3320 from 3600, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 11:
2800 divided by 830 is 3 with a remainder of 310.
Record the quotient 3 as the next digit in the result. 
Result so far: 101251.643
If we subtract 2490 from 2800, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 12:
830 goes into 3100 3 times with a remainder of 610.
The number 3 becomes the next digit in our result. 
Result so far: 101251.6433
The remainder is 610 after subtracting 2490 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

In conclusion, the division gives 101251.6433 with a balance of 0.0061.
