We look at the division of 75391832 by 970 
The aim is to understand the frequency of 970 in 75391832.

Going ahead to step 1:
The number 970 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 970

Step 2:
When dividing 75 by 970, we get 0 with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Take the next digit (3) from the dividend and append it to 75, then repeat: 753 / 970

On to step 3:
970 can be fit into 753 0 times, resulting in a remainder of 753.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 753 to get 753.
Take the next digit (9) from the dividend and append it to 753, then repeat: 7539 / 970

Moving on to step 4:
The number 970 fits into 7539 7 times, leaving a remainder of 749.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 6790 away from 7539, we end up with 749.
Bring next digit (1) of the dividend behind the 749 and repeat the process: 7491 / 970

Let's proceed to step 5:
970 can be fit into 7491 7 times, resulting in a remainder of 701.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
Deduct 6790 from 7491 and we're left with 701.
Bring next digit (8) of the dividend behind the 701 and repeat the process: 7018 / 970

Moving on to step 6:
970 can be fit into 7018 7 times, resulting in a remainder of 228.
Use 7 as the next digit of our solution. 
Result so far: 777.0
Subtract 6790 from 7018 to get 228.
Bring next digit (3) of the dividend behind the 228 and repeat the process: 2283 / 970

Let's proceed to step 7:
970 goes into 2283 2 times with a remainder of 343.
Use 2 as the next digit of our solution. 
Result so far: 7772.0
Deduct 1940 from 2283 and we're left with 343.
Fetch the next digit (2) from the dividend, attach it to 343 and continue: 3432 / 970

Let's proceed to step 8:
If we divide 3432 by 970, we get 3 and a remainder of 522.
Write down 3 as next digit of the result. 
Result so far: 77723.0
If we take 2910 away from 3432, we end up with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Moving on to step 9:
If we divide 5220 by 970, we get 5 and a remainder of 370.
The next digit of our result is 5. 
Result so far: 77723.5
If we subtract 4850 from 5220, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 10:
970 can be fit into 3700 3 times, resulting in a remainder of 790.
The number 3 becomes the next digit in our result. 
Result so far: 77723.53
The remainder is 790 after subtracting 2910 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Advancing to step 11:
7900 divided by 970 is 8 with a remainder of 140.
Record the quotient 8 as the next digit in the result. 
Result so far: 77723.538
Subtract 7760 from 7900 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 12:
If we divide 1400 by 970, we get 1 and a remainder of 430.
Write down 1 as next digit of the result. 
Result so far: 77723.5381
Deduct 970 from 1400 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 13:
4300 divided by 970 is 4 with a remainder of 420.
Use 4 as the next digit of our solution. 
Result so far: 77723.53814
If we take 3880 away from 4300, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 14:
970 goes into 4200 4 times with a remainder of 320.
Put 4 as the next digit of the answer. 
Result so far: 77723.538144
Deduct 3880 from 4200 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final result is 77723.538144 with a remainder of 3.2e-05.
