We look at the division of 39407101 by 970 
The aim is to understand the frequency of 970 in 39407101.

On to step 1:
970 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 970

Let's proceed to step 2:
The number 970 fits into 39 0 times, leaving a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 970

Let's proceed to step 3:
If we divide 394 by 970, we get 0 and a remainder of 394.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 394 to get 394.
Include the next digit (0) from the dividend after 394, then repeat: 3940 / 970

Moving on to step 4:
970 can be fit into 3940 4 times, resulting in a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 3880 away from 3940, we end up with 60.
Include the next digit (7) from the dividend after 60, then repeat: 607 / 970

Advancing to step 5:
970 can be fit into 607 0 times, resulting in a remainder of 607.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtract 0 from 607 to get 607.
Append the next digit (1) from the dividend to 607 and continue with: 6071 / 970

Going ahead to step 6:
When dividing 6071 by 970, we get 6 with a remainder of 251.
The number 6 becomes the next digit in our result. 
Result so far: 406.0
Deduct 5820 from 6071 and we're left with 251.
Take the next digit (0) from the dividend and append it to 251, then repeat: 2510 / 970

Step 7:
970 can be fit into 2510 2 times, resulting in a remainder of 570.
The next digit of our result is 2. 
Result so far: 4062.0
The remainder is 570 after subtracting 1940 from 2510.
Include the next digit (1) from the dividend after 570, then repeat: 5701 / 970

Moving on to step 8:
When dividing 5701 by 970, we get 5 with a remainder of 851.
The number 5 becomes the next digit in our result. 
Result so far: 40625.0
If we subtract 4850 from 5701, we get 851.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8510, and continue the process.

Let's proceed to step 9:
The number 970 fits into 8510 8 times, leaving a remainder of 750.
Put 8 as the next digit of the answer. 
Result so far: 40625.8
Subtract 7760 from 8510 to get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Advancing to step 10:
The number 970 fits into 7500 7 times, leaving a remainder of 710.
Put 7 as the next digit of the answer. 
Result so far: 40625.87
If we subtract 6790 from 7500, we get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Step 11:
970 goes into 7100 7 times with a remainder of 310.
Write down 7 as next digit of the result. 
Result so far: 40625.877
Deduct 6790 from 7100 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

The final outcome is 40625.877, with a leftover of 0.031.
