We're dividing 55430076 by 980 
The aim is to understand the frequency of 980 in 55430076.

On to step 1:
If we divide 5 by 980, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 980

Advancing to step 2:
980 goes into 55 0 times with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Include the next digit (4) from the dividend after 55, then repeat: 554 / 980

On to step 3:
If we divide 554 by 980, we get 0 and a remainder of 554.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 554, we end up with 554.
Grab the next digit (3) from the dividend, add it to 554, then carry on: 5543 / 980

Moving on to step 4:
5543 divided by 980 is 5 with a remainder of 643.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 643 after subtracting 4900 from 5543.
Take the next digit (0) from the dividend and append it to 643, then repeat: 6430 / 980

Let's proceed to step 5:
If we divide 6430 by 980, we get 6 and a remainder of 550.
Use 6 as the next digit of our solution. 
Result so far: 56.0
Deduct 5880 from 6430 and we're left with 550.
Grab the next digit (0) from the dividend, add it to 550, then carry on: 5500 / 980

Step 6:
If we divide 5500 by 980, we get 5 and a remainder of 600.
The number 5 becomes the next digit in our result. 
Result so far: 565.0
Subtracting 4900 from 5500 leaves us with 600.
Fetch the next digit (7) from the dividend, attach it to 600 and continue: 6007 / 980

Step 7:
980 goes into 6007 6 times with a remainder of 127.
Record the quotient 6 as the next digit in the result. 
Result so far: 5656.0
Subtract 5880 from 6007 to get 127.
Fetch the next digit (6) from the dividend, attach it to 127 and continue: 1276 / 980

Advancing to step 8:
1276 divided by 980 is 1 with a remainder of 296.
Use 1 as the next digit of our solution. 
Result so far: 56561.0
Subtracting 980 from 1276 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 9:
2960 divided by 980 is 3 with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 56561.3
If we subtract 2940 from 2960, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
When dividing 200 by 980, we get 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 56561.3
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 11:
2000 divided by 980 is 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 56561.302
The remainder is 40 after subtracting 1960 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
If we divide 400 by 980, we get 0 and a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 56561.302
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 13:
The number 980 fits into 4000 4 times, leaving a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 56561.30204
If we take 3920 away from 4000, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
The number 980 fits into 800 0 times, leaving a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 56561.30204
Subtract 0 from 800 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.

Advancing to step 15:
When dividing 8000 by 980, we get 8 with a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 56561.3020408
If we subtract 7840 from 8000, we 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.

Going ahead to step 16:
If we divide 1600 by 980, we get 1 and a remainder of 620.
The number 1 becomes the next digit in our result. 
Result so far: 56561.30204081
Deduct 980 from 1600 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

The final result is 56561.30204081 with a remainder of 6.2e-07.
