Let's divide 7125808 by 730
The aim is to understand the frequency of 730 in 7125808.

Advancing to step 1:
730 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 730

Step 2:
730 can be fit into 71 0 times, resulting in a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Append the next digit (2) from the dividend to 71 and continue with: 712 / 730

Step 3:
The number 730 fits into 712 0 times, leaving a remainder of 712.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 712 leaves us with 712.
Grab the next digit (5) from the dividend, add it to 712, then carry on: 7125 / 730

On to step 4:
When dividing 7125 by 730, we get 9 with a remainder of 555.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 6570 from 7125 leaves us with 555.
Take the next digit (8) from the dividend and append it to 555, then repeat: 5558 / 730

Step 5:
5558 divided by 730 is 7 with a remainder of 448.
The next digit of our result is 7. 
Result so far: 97.0
Subtract 5110 from 5558 to get 448.
Bring next digit (0) of the dividend behind the 448 and repeat the process: 4480 / 730

Let's proceed to step 6:
The number 730 fits into 4480 6 times, leaving a remainder of 100.
Write down 6 as next digit of the result. 
Result so far: 976.0
The remainder is 100 after subtracting 4380 from 4480.
Grab the next digit (8) from the dividend, add it to 100, then carry on: 1008 / 730

Moving on to step 7:
If we divide 1008 by 730, we get 1 and a remainder of 278.
Put 1 as the next digit of the answer. 
Result so far: 9761.0
Subtracting 730 from 1008 leaves us with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Going ahead to step 8:
2780 divided by 730 is 3 with a remainder of 590.
The next digit of our result is 3. 
Result so far: 9761.3
The remainder is 590 after subtracting 2190 from 2780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

On to step 9:
When dividing 5900 by 730, we get 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 9761.38
Subtracting 5840 from 5900 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
730 can be fit into 600 0 times, resulting in a remainder of 600.
The next digit of our result is 0. 
Result so far: 9761.38
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 11:
The number 730 fits into 6000 8 times, leaving a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 9761.3808
Subtract 5840 from 6000 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.

Moving on to step 12:
When dividing 1600 by 730, we get 2 with a remainder of 140.
The next digit of our result is 2. 
Result so far: 9761.38082
If we take 1460 away from 1600, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 13:
1400 divided by 730 is 1 with a remainder of 670.
Put 1 as the next digit of the answer. 
Result so far: 9761.380821
Subtract 730 from 1400 to get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

On to step 14:
If we divide 6700 by 730, we get 9 and a remainder of 130.
Record the quotient 9 as the next digit in the result. 
Result so far: 9761.3808219
If we subtract 6570 from 6700, 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.

Advancing to step 15:
730 can be fit into 1300 1 times, resulting in a remainder of 570.
The next digit of our result is 1. 
Result so far: 9761.38082191
Deduct 730 from 1300 and we're left with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

The final outcome is 9761.38082191, with a leftover of 5.7e-07.
