Let's divide 158688 by 70
The aim is to understand the frequency of 70 in 158688.

Step 1:
70 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 70

Let's proceed to step 2:
15 divided by 70 is 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 70

On to step 3:
If we divide 158 by 70, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 140 from 158 leaves us with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 70

Going ahead to step 4:
When dividing 186 by 70, we get 2 with a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we take 140 away from 186, we end up with 46.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 70

On to step 5:
70 goes into 468 6 times with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 226.0
The remainder is 48 after subtracting 420 from 468.
Bring next digit (8) of the dividend behind the 48 and repeat the process: 488 / 70

Let's proceed to step 6:
70 can be fit into 488 6 times, resulting in a remainder of 68.
The next digit of our result is 6. 
Result so far: 2266.0
Subtract 420 from 488 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 7:
When dividing 680 by 70, we get 9 with a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 2266.9
The remainder is 50 after subtracting 630 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
500 divided by 70 is 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 2266.97
Subtracting 490 from 500 leaves us 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.

Going ahead to step 9:
When dividing 100 by 70, we get 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 2266.971
If we take 70 away from 100, 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.

Let's proceed to step 10:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 2266.9714
If we take 280 away from 300, we end up 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 11:
The number 70 fits into 200 2 times, leaving a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 2266.97142
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.

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: 2266.971428
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.

Going ahead to step 13:
If we divide 400 by 70, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 2266.9714285
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.

Advancing to step 14:
When dividing 500 by 70, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 2266.97142857
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.

The final outcome is 2266.97142857, with a leftover of 1e-08.
