We're dividing 65815049 by 980 
The aim is to understand the frequency of 980 in 65815049.

Going ahead to step 1:
980 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 980

Moving on to step 2:
980 goes into 65 0 times with a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 65 after subtracting 0 from 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 980

On to step 3:
980 can be fit into 658 0 times, resulting in a remainder of 658.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 658 and we're left with 658.
Bring next digit (1) of the dividend behind the 658 and repeat the process: 6581 / 980

On to step 4:
If we divide 6581 by 980, we get 6 and a remainder of 701.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 701 after subtracting 5880 from 6581.
Bring next digit (5) of the dividend behind the 701 and repeat the process: 7015 / 980

On to step 5:
980 goes into 7015 7 times with a remainder of 155.
Put 7 as the next digit of the answer. 
Result so far: 67.0
Subtract 6860 from 7015 to get 155.
Fetch the next digit (0) from the dividend, attach it to 155 and continue: 1550 / 980

On to step 6:
When dividing 1550 by 980, we get 1 with a remainder of 570.
Use 1 as the next digit of our solution. 
Result so far: 671.0
Subtract 980 from 1550 to get 570.
Append the next digit (4) from the dividend to 570 and continue with: 5704 / 980

Moving on to step 7:
If we divide 5704 by 980, we get 5 and a remainder of 804.
Record the quotient 5 as the next digit in the result. 
Result so far: 6715.0
If we take 4900 away from 5704, we end up with 804.
Fetch the next digit (9) from the dividend, attach it to 804 and continue: 8049 / 980

On to step 8:
980 goes into 8049 8 times with a remainder of 209.
Record the quotient 8 as the next digit in the result. 
Result so far: 67158.0
Subtract 7840 from 8049 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

On to step 9:
When dividing 2090 by 980, we get 2 with a remainder of 130.
Record the quotient 2 as the next digit in the result. 
Result so far: 67158.2
If we subtract 1960 from 2090, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 10:
The number 980 fits into 1300 1 times, leaving a remainder of 320.
Use 1 as the next digit of our solution. 
Result so far: 67158.21
Subtract 980 from 1300 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 11:
980 can be fit into 3200 3 times, resulting in a remainder of 260.
Use 3 as the next digit of our solution. 
Result so far: 67158.213
Deduct 2940 from 3200 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 12:
When dividing 2600 by 980, we get 2 with a remainder of 640.
Record the quotient 2 as the next digit in the result. 
Result so far: 67158.2132
If we take 1960 away from 2600, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 13:
6400 divided by 980 is 6 with a remainder of 520.
The number 6 becomes the next digit in our result. 
Result so far: 67158.21326
The remainder is 520 after subtracting 5880 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 14:
5200 divided by 980 is 5 with a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 67158.213265
Subtract 4900 from 5200 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 15:
3000 divided by 980 is 3 with a remainder of 60.
The next digit of our result is 3. 
Result so far: 67158.2132653
Subtract 2940 from 3000 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 16:
If we divide 600 by 980, we get 0 and a remainder of 600.
The next digit of our result is 0. 
Result so far: 67158.2132653
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final outcome is 67158.2132653, with a leftover of 6e-07.
