63172 ÷ 70 
The aim is to understand the frequency of 70 in 63172.

On to step 1:
70 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 70

Step 2:
63 divided by 70 is 0 with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Take the next digit (1) from the dividend and append it to 63, then repeat: 631 / 70

Step 3:
70 can be fit into 631 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 630 away from 631, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 70

Let's proceed to step 4:
The number 70 fits into 17 0 times, leaving a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 90.0
Subtract 0 from 17 to get 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 70

Moving on to step 5:
172 divided by 70 is 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 902.0
Subtract 140 from 172 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 6:
If we divide 320 by 70, we get 4 and a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 902.4
If we take 280 away from 320, we end up 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.

On to step 7:
70 goes into 400 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 902.45
Deduct 350 from 400 and we're left 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.

Moving on to step 8:
70 goes into 500 7 times with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 902.457
If we subtract 490 from 500, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
100 divided by 70 is 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 902.4571
Subtract 70 from 100 to 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.

Step 10:
70 goes into 300 4 times with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 902.45714
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.

Going ahead to step 11:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 902.457142
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
If we divide 600 by 70, we get 8 and a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 902.4571428
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.

Advancing to step 13:
400 divided by 70 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 902.45714285
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 902.45714285 with a remainder of 5e-08.
