We're dividing 80851642 by 970 
The aim is to understand the frequency of 970 in 80851642.

Let's proceed to step 1:
The number 970 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 970

On to step 2:
If we divide 80 by 970, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Append the next digit (8) from the dividend to 80 and continue with: 808 / 970

Advancing to step 3:
The number 970 fits into 808 0 times, leaving a remainder of 808.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 808, we get 808.
Append the next digit (5) from the dividend to 808 and continue with: 8085 / 970

Moving on to step 4:
970 goes into 8085 8 times with a remainder of 325.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 7760 from 8085 to get 325.
Take the next digit (1) from the dividend and append it to 325, then repeat: 3251 / 970

Advancing to step 5:
3251 divided by 970 is 3 with a remainder of 341.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Deduct 2910 from 3251 and we're left with 341.
Grab the next digit (6) from the dividend, add it to 341, then carry on: 3416 / 970

Let's proceed to step 6:
970 can be fit into 3416 3 times, resulting in a remainder of 506.
The number 3 becomes the next digit in our result. 
Result so far: 833.0
If we take 2910 away from 3416, we end up with 506.
Grab the next digit (4) from the dividend, add it to 506, then carry on: 5064 / 970

Going ahead to step 7:
If we divide 5064 by 970, we get 5 and a remainder of 214.
The next digit of our result is 5. 
Result so far: 8335.0
Subtract 4850 from 5064 to get 214.
Include the next digit (2) from the dividend after 214, then repeat: 2142 / 970

Going ahead to step 8:
The number 970 fits into 2142 2 times, leaving a remainder of 202.
Write down 2 as next digit of the result. 
Result so far: 83352.0
If we subtract 1940 from 2142, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 9:
2020 divided by 970 is 2 with a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 83352.2
Subtracting 1940 from 2020 leaves us 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 10:
970 can be fit into 800 0 times, resulting in a remainder of 800.
Use 0 as the next digit of our solution. 
Result so far: 83352.2
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 11:
When dividing 8000 by 970, we get 8 with a remainder of 240.
The number 8 becomes the next digit in our result. 
Result so far: 83352.208
Subtract 7760 from 8000 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 12:
When dividing 2400 by 970, we get 2 with a remainder of 460.
Write down 2 as next digit of the result. 
Result so far: 83352.2082
Deduct 1940 from 2400 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 13:
If we divide 4600 by 970, we get 4 and a remainder of 720.
Use 4 as the next digit of our solution. 
Result so far: 83352.20824
The remainder is 720 after subtracting 3880 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 14:
When dividing 7200 by 970, we get 7 with a remainder of 410.
Put 7 as the next digit of the answer. 
Result so far: 83352.208247
Deduct 6790 from 7200 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 15:
970 goes into 4100 4 times with a remainder of 220.
Record the quotient 4 as the next digit in the result. 
Result so far: 83352.2082474
The remainder is 220 after subtracting 3880 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 16:
The number 970 fits into 2200 2 times, leaving a remainder of 260.
Write down 2 as next digit of the result. 
Result so far: 83352.20824742
If we take 1940 away from 2200, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

In conclusion, the division gives 83352.20824742 with a balance of 2.6e-07.
