7986492 ÷ 980 
The aim is to understand the frequency of 980 in 7986492.

Going ahead to step 1:
If we divide 7 by 980, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 980

Step 2:
If we divide 79 by 980, we get 0 and a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Include the next digit (8) from the dividend after 79, then repeat: 798 / 980

Going ahead to step 3:
980 can be fit into 798 0 times, resulting in a remainder of 798.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 798 to get 798.
Grab the next digit (6) from the dividend, add it to 798, then carry on: 7986 / 980

Moving on to step 4:
7986 divided by 980 is 8 with a remainder of 146.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 7840 from 7986, we get 146.
Bring next digit (4) of the dividend behind the 146 and repeat the process: 1464 / 980

Going ahead to step 5:
980 goes into 1464 1 times with a remainder of 484.
The next digit of our result is 1. 
Result so far: 81.0
Subtract 980 from 1464 to get 484.
Take the next digit (9) from the dividend and append it to 484, then repeat: 4849 / 980

Advancing to step 6:
When dividing 4849 by 980, we get 4 with a remainder of 929.
The number 4 becomes the next digit in our result. 
Result so far: 814.0
If we subtract 3920 from 4849, we get 929.
Take the next digit (2) from the dividend and append it to 929, then repeat: 9292 / 980

On to step 7:
When dividing 9292 by 980, we get 9 with a remainder of 472.
The number 9 becomes the next digit in our result. 
Result so far: 8149.0
The remainder is 472 after subtracting 8820 from 9292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Advancing to step 8:
980 goes into 4720 4 times with a remainder of 800.
Put 4 as the next digit of the answer. 
Result so far: 8149.4
Subtract 3920 from 4720 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 9:
980 can be fit into 8000 8 times, resulting in a remainder of 160.
The next digit of our result is 8. 
Result so far: 8149.48
Subtract 7840 from 8000 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 10:
980 can be fit into 1600 1 times, resulting in a remainder of 620.
Write down 1 as next digit of the result. 
Result so far: 8149.481
If we subtract 980 from 1600, 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 11:
980 can be fit into 6200 6 times, resulting in a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 8149.4816
Subtract 5880 from 6200 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.

Advancing to step 12:
If we divide 3200 by 980, we get 3 and a remainder of 260.
Put 3 as the next digit of the answer. 
Result so far: 8149.48163
The remainder is 260 after subtracting 2940 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 13:
980 goes into 2600 2 times with a remainder of 640.
Use 2 as the next digit of our solution. 
Result so far: 8149.481632
The remainder is 640 after subtracting 1960 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 14:
980 goes into 6400 6 times with a remainder of 520.
Write down 6 as next digit of the result. 
Result so far: 8149.4816326
Deduct 5880 from 6400 and we're left with 520.
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 15:
980 can be fit into 5200 5 times, resulting in a remainder of 300.
Record the quotient 5 as the next digit in the result. 
Result so far: 8149.48163265
The remainder is 300 after subtracting 4900 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 8149.48163265, with a leftover of 3e-07.
