We look at the division of 84280920 by 997 
We want to divide 84280920 by 997.

Step 1:
When dividing 8 by 997, 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 / 997

Advancing to step 2:
When dividing 84 by 997, we get 0 with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Include the next digit (2) from the dividend after 84, then repeat: 842 / 997

On to step 3:
If we divide 842 by 997, we get 0 and a remainder of 842.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 842, we get 842.
Append the next digit (8) from the dividend to 842 and continue with: 8428 / 997

Moving on to step 4:
997 can be fit into 8428 8 times, resulting in a remainder of 452.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 7976 from 8428 to get 452.
Take the next digit (0) from the dividend and append it to 452, then repeat: 4520 / 997

Going ahead to step 5:
If we divide 4520 by 997, we get 4 and a remainder of 532.
Put 4 as the next digit of the answer. 
Result so far: 84.0
If we take 3988 away from 4520, we end up with 532.
Include the next digit (9) from the dividend after 532, then repeat: 5329 / 997

Step 6:
5329 divided by 997 is 5 with a remainder of 344.
Write down 5 as next digit of the result. 
Result so far: 845.0
Subtract 4985 from 5329 to get 344.
Include the next digit (2) from the dividend after 344, then repeat: 3442 / 997

Going ahead to step 7:
3442 divided by 997 is 3 with a remainder of 451.
Put 3 as the next digit of the answer. 
Result so far: 8453.0
Subtract 2991 from 3442 to get 451.
Append the next digit (0) from the dividend to 451 and continue with: 4510 / 997

Moving on to step 8:
997 goes into 4510 4 times with a remainder of 522.
The next digit of our result is 4. 
Result so far: 84534.0
Subtracting 3988 from 4510 leaves us with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Step 9:
When dividing 5220 by 997, we get 5 with a remainder of 235.
Put 5 as the next digit of the answer. 
Result so far: 84534.5
If we subtract 4985 from 5220, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 10:
997 goes into 2350 2 times with a remainder of 356.
The number 2 becomes the next digit in our result. 
Result so far: 84534.52
Subtracting 1994 from 2350 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 11:
When dividing 3560 by 997, we get 3 with a remainder of 569.
Write down 3 as next digit of the result. 
Result so far: 84534.523
Subtract 2991 from 3560 to get 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Advancing to step 12:
If we divide 5690 by 997, we get 5 and a remainder of 705.
Use 5 as the next digit of our solution. 
Result so far: 84534.5235
Subtract 4985 from 5690 to get 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Step 13:
If we divide 7050 by 997, we get 7 and a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 84534.52357
If we take 6979 away from 7050, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 14:
997 goes into 710 0 times with a remainder of 710.
Record the quotient 0 as the next digit in the result. 
Result so far: 84534.52357
Deduct 0 from 710 and we're left with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Step 15:
When dividing 7100 by 997, we get 7 with a remainder of 121.
Put 7 as the next digit of the answer. 
Result so far: 84534.5235707
Subtract 6979 from 7100 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 16:
1210 divided by 997 is 1 with a remainder of 213.
The number 1 becomes the next digit in our result. 
Result so far: 84534.52357071
If we take 997 away from 1210, we end up with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

The final result is 84534.52357071 with a remainder of 2.13e-07.
