We look at the division of 358691 by 70 
The aim is to understand the frequency of 70 in 358691.

Moving on to step 1:
The number 70 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 70

On to step 2:
When dividing 35 by 70, we get 0 with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Fetch the next digit (8) from the dividend, attach it to 35 and continue: 358 / 70

Moving on to step 3:
When dividing 358 by 70, we get 5 with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 350 from 358, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 70

Moving on to step 4:
70 goes into 86 1 times with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
If we subtract 70 from 86, we get 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 70

Let's proceed to step 5:
70 can be fit into 169 2 times, resulting in a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 512.0
If we take 140 away from 169, we end up with 29.
Take the next digit (1) from the dividend and append it to 29, then repeat: 291 / 70

Step 6:
70 goes into 291 4 times with a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 5124.0
The remainder is 11 after subtracting 280 from 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
When dividing 110 by 70, we get 1 with a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 5124.1
Deduct 70 from 110 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.

Moving on to step 8:
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: 5124.15
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.

On to step 9:
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: 5124.157
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.

Step 10:
100 divided by 70 is 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 5124.1571
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.

On to step 11:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 5124.15714
Subtract 280 from 300 to 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.

Going ahead to step 12:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 5124.157142
Deduct 140 from 200 and we're left 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 13:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 5124.1571428
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.

Step 14:
The number 70 fits into 400 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 5124.15714285
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.

The final result is 5124.15714285 with a remainder of 5e-08.
