Let's divide 12090421 by 130
The aim is to understand the frequency of 130 in 12090421.

Moving on to step 1:
When dividing 1 by 130, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 130

Going ahead to step 2:
12 divided by 130 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 130

Step 3:
The number 130 fits into 120 0 times, leaving a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 120, we get 120.
Fetch the next digit (9) from the dividend, attach it to 120 and continue: 1209 / 130

Advancing to step 4:
130 can be fit into 1209 9 times, resulting in a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 39 after subtracting 1170 from 1209.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 130

Moving on to step 5:
390 divided by 130 is 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
If we subtract 390 from 390, we get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 130

Moving on to step 6:
When dividing 4 by 130, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 930.0
If we take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 130

On to step 7:
When dividing 42 by 130, we get 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 9300.0
If we subtract 0 from 42, we get 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 130

Moving on to step 8:
130 goes into 421 3 times with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 93003.0
Subtracting 390 from 421 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 9:
If we divide 310 by 130, we get 2 and a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 93003.2
If we take 260 away from 310, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
When dividing 500 by 130, we get 3 with a remainder of 110.
Put 3 as the next digit of the answer. 
Result so far: 93003.23
Deduct 390 from 500 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 11:
130 goes into 1100 8 times with a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 93003.238
If we subtract 1040 from 1100, we 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 12:
If we divide 600 by 130, we get 4 and a remainder of 80.
The next digit of our result is 4. 
Result so far: 93003.2384
Deduct 520 from 600 and we're left 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.

Advancing to step 13:
130 can be fit into 800 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 93003.23846
The remainder is 20 after subtracting 780 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
130 can be fit into 200 1 times, resulting in a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 93003.238461
The remainder is 70 after subtracting 130 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 15:
130 goes into 700 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 93003.2384615
Subtracting 650 from 700 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 16:
130 can be fit into 500 3 times, resulting in a remainder of 110.
Put 3 as the next digit of the answer. 
Result so far: 93003.23846153
If we subtract 390 from 500, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The quotient of the division is 93003.23846153, and the remainder is 1.1e-07.
