We divide 84451617 by 980
We want to divide 84451617 by 980.

Step 1:
8 divided by 980 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 980

On to step 2:
The number 980 fits into 84 0 times, leaving 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.
Include the next digit (4) from the dividend after 84, then repeat: 844 / 980

Advancing to step 3:
980 goes into 844 0 times with a remainder of 844.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 844 and we're left with 844.
Grab the next digit (5) from the dividend, add it to 844, then carry on: 8445 / 980

On to step 4:
The number 980 fits into 8445 8 times, leaving a remainder of 605.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 7840 from 8445, we get 605.
Bring next digit (1) of the dividend behind the 605 and repeat the process: 6051 / 980

Going ahead to step 5:
When dividing 6051 by 980, we get 6 with a remainder of 171.
Use 6 as the next digit of our solution. 
Result so far: 86.0
If we take 5880 away from 6051, we end up with 171.
Bring next digit (6) of the dividend behind the 171 and repeat the process: 1716 / 980

Step 6:
980 goes into 1716 1 times with a remainder of 736.
Put 1 as the next digit of the answer. 
Result so far: 861.0
Deduct 980 from 1716 and we're left with 736.
Take the next digit (1) from the dividend and append it to 736, then repeat: 7361 / 980

On to step 7:
If we divide 7361 by 980, we get 7 and a remainder of 501.
The number 7 becomes the next digit in our result. 
Result so far: 8617.0
Deduct 6860 from 7361 and we're left with 501.
Bring next digit (7) of the dividend behind the 501 and repeat the process: 5017 / 980

Advancing to step 8:
If we divide 5017 by 980, we get 5 and a remainder of 117.
Use 5 as the next digit of our solution. 
Result so far: 86175.0
The remainder is 117 after subtracting 4900 from 5017.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Going ahead to step 9:
If we divide 1170 by 980, we get 1 and a remainder of 190.
The next digit of our result is 1. 
Result so far: 86175.1
If we subtract 980 from 1170, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 10:
980 can be fit into 1900 1 times, resulting in a remainder of 920.
Write down 1 as next digit of the result. 
Result so far: 86175.11
Subtracting 980 from 1900 leaves us with 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9200, and continue the process.

The final outcome is 86175.11, with a leftover of 0.92.
