We look at the division of 22372843 by 70 
The aim is to understand the frequency of 70 in 22372843.

On to step 1:
If we divide 2 by 70, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 70

On to step 2:
The number 70 fits into 22 0 times, leaving a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 22 and we're left with 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 70

Step 3:
The number 70 fits into 223 3 times, leaving a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 210 from 223 and we're left with 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 70

Step 4:
137 divided by 70 is 1 with a remainder of 67.
The next digit of our result is 1. 
Result so far: 31.0
Subtracting 70 from 137 leaves us with 67.
Bring next digit (2) of the dividend behind the 67 and repeat the process: 672 / 70

Advancing to step 5:
When dividing 672 by 70, we get 9 with a remainder of 42.
The next digit of our result is 9. 
Result so far: 319.0
Deduct 630 from 672 and we're left with 42.
Take the next digit (8) from the dividend and append it to 42, then repeat: 428 / 70

Moving on to step 6:
70 goes into 428 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 3196.0
Subtracting 420 from 428 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 70

Advancing to step 7:
The number 70 fits into 84 1 times, leaving a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 31961.0
Subtract 70 from 84 to get 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 70

Going ahead to step 8:
143 divided by 70 is 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 319612.0
Subtracting 140 from 143 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
70 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 319612.0
The remainder is 30 after subtracting 0 from 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 10:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 319612.04
If we subtract 280 from 300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
70 goes into 200 2 times with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 319612.042
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.

Going ahead to step 12:
600 divided by 70 is 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 319612.0428
Subtract 560 from 600 to 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.

Step 13:
70 goes into 400 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 319612.04285
Subtract 350 from 400 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
70 goes into 500 7 times with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 319612.042857
The remainder is 10 after subtracting 490 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 15:
When dividing 100 by 70, we get 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 319612.0428571
If we subtract 70 from 100, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 16:
300 divided by 70 is 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 319612.04285714
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.

The quotient of the division is 319612.04285714, and the remainder is 2e-08.
