63931 ÷ 70 
The aim is to understand the frequency of 70 in 63931.

Let's proceed to step 1:
70 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 70

Let's proceed to step 2:
The number 70 fits into 63 0 times, leaving a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 70

On to step 3:
If we divide 639 by 70, we get 9 and a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 630 from 639 leaves us with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 70

Moving on to step 4:
70 goes into 93 1 times with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 91.0
If we subtract 70 from 93, we get 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 70

Going ahead to step 5:
When dividing 231 by 70, we get 3 with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 913.0
If we take 210 away from 231, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 6:
The number 70 fits into 210 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 913.3
Subtracting 210 from 210 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
0 divided by 70 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 913.3
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
The number 70 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 913.3
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 913.3 and a remainder of 0.0.
