We're dividing 371923 by 70 
The aim is to understand the frequency of 70 in 371923.

Let's proceed to step 1:
The number 70 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 70

Step 2:
70 can be fit into 37 0 times, resulting in a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 70

Step 3:
70 goes into 371 5 times with a remainder of 21.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 350 from 371 leaves us with 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 70

Step 4:
The number 70 fits into 219 3 times, leaving a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 53.0
Subtracting 210 from 219 leaves us with 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 70

Moving on to step 5:
70 can be fit into 92 1 times, resulting in a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 531.0
Deduct 70 from 92 and we're left with 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 70

Moving on to step 6:
If we divide 223 by 70, we get 3 and a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 5313.0
If we subtract 210 from 223, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
When dividing 130 by 70, we get 1 with a remainder of 60.
Put 1 as the next digit of the answer. 
Result so far: 5313.1
If we take 70 away from 130, we end up 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.

On to step 8:
600 divided by 70 is 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 5313.18
If we take 560 away from 600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
The number 70 fits into 400 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 5313.185
Subtracting 350 from 400 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.

Step 10:
70 goes into 500 7 times with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 5313.1857
Subtract 490 from 500 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
If we divide 100 by 70, we get 1 and a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 5313.18571
Subtracting 70 from 100 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
If we divide 300 by 70, we get 4 and a remainder of 20.
The next digit of our result is 4. 
Result so far: 5313.185714
Subtracting 280 from 300 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
If we divide 200 by 70, we get 2 and a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 5313.1857142
Subtracting 140 from 200 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.

On to step 14:
70 goes into 600 8 times with a remainder of 40.
The next digit of our result is 8. 
Result so far: 5313.18571428
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 5313.18571428 with a remainder of 4e-08.
