We look at the division of 23942544 by 70 
The aim is to understand the frequency of 70 in 23942544.

Step 1:
When dividing 2 by 70, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 70

Advancing to step 2:
23 divided by 70 is 0 with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 70

Advancing to step 3:
The number 70 fits into 239 3 times, leaving a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 210 from 239 and we're left with 29.
Grab the next digit (4) from the dividend, add it to 29, then carry on: 294 / 70

On to step 4:
If we divide 294 by 70, we get 4 and a remainder of 14.
The next digit of our result is 4. 
Result so far: 34.0
Subtracting 280 from 294 leaves us with 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 70

Step 5:
If we divide 142 by 70, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 342.0
The remainder is 2 after subtracting 140 from 142.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 70

Let's proceed to step 6:
70 goes into 25 0 times with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 3420.0
If we take 0 away from 25, we end up with 25.
Bring next digit (4) of the dividend behind the 25 and repeat the process: 254 / 70

Let's proceed to step 7:
254 divided by 70 is 3 with a remainder of 44.
Write down 3 as next digit of the result. 
Result so far: 34203.0
Subtract 210 from 254 to get 44.
Include the next digit (4) from the dividend after 44, then repeat: 444 / 70

Going ahead to step 8:
The number 70 fits into 444 6 times, leaving a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 342036.0
The remainder is 24 after subtracting 420 from 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
70 can be fit into 240 3 times, resulting in a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 342036.3
If we take 210 away from 240, we end up 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.

Advancing to step 10:
70 goes into 300 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 342036.34
Deduct 280 from 300 and we're left 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.

Step 11:
When dividing 200 by 70, we get 2 with a remainder of 60.
The next digit of our result is 2. 
Result so far: 342036.342
If we take 140 away from 200, 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 12:
70 goes into 600 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 342036.3428
Deduct 560 from 600 and we're left 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.

Going ahead to step 13:
If we divide 400 by 70, we get 5 and a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 342036.34285
The remainder is 50 after subtracting 350 from 400.
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:
If we divide 500 by 70, we get 7 and a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 342036.342857
If we take 490 away from 500, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 15:
100 divided by 70 is 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 342036.3428571
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On 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: 342036.34285714
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.

After the division, we end up with 342036.34285714 and a remainder of 2e-08.
