We look at the division of 112831 by 70 
The aim is to understand the frequency of 70 in 112831.

Going ahead to step 1:
The number 70 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 70

Step 2:
When dividing 11 by 70, we get 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 70

Let's proceed to step 3:
If we divide 112 by 70, we get 1 and a remainder of 42.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 70 from 112, we get 42.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 70

Moving on to step 4:
If we divide 428 by 70, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 420 away from 428, we end up with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 70

Going ahead to step 5:
70 goes into 83 1 times with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 161.0
Subtract 70 from 83 to get 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 70

Step 6:
70 can be fit into 131 1 times, resulting in a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 1611.0
Subtracting 70 from 131 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 7:
If we divide 610 by 70, we get 8 and a remainder of 50.
Use 8 as the next digit of our solution. 
Result so far: 1611.8
Subtract 560 from 610 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.

Going ahead to step 8:
If we divide 500 by 70, we get 7 and a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 1611.87
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.

Step 9:
When dividing 100 by 70, we get 1 with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1611.871
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.

Let's proceed to step 10:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 1611.8714
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
70 goes into 200 2 times with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 1611.87142
Subtract 140 from 200 to get 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.
The next digit of our result is 8. 
Result so far: 1611.871428
Subtracting 560 from 600 leaves us 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 13:
The number 70 fits into 400 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 1611.8714285
If we subtract 350 from 400, we 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.

Let's proceed to step 14:
When dividing 500 by 70, we get 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 1611.87142857
Deduct 490 from 500 and we're left 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 result is 1611.87142857 with a remainder of 1e-08.
