We divide 813225 by 70
The aim is to understand the frequency of 70 in 813225.

Moving on to step 1:
8 divided by 70 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 70

Advancing to step 2:
If we divide 81 by 70, we get 1 and a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 70 from 81 and we're left with 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 70

On to step 3:
If we divide 113 by 70, we get 1 and a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 70 from 113 and we're left with 43.
Take the next digit (2) from the dividend and append it to 43, then repeat: 432 / 70

Advancing to step 4:
70 goes into 432 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 116.0
Deduct 420 from 432 and we're left with 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 70

Moving on to step 5:
70 goes into 122 1 times with a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 1161.0
Subtract 70 from 122 to get 52.
Append the next digit (5) from the dividend to 52 and continue with: 525 / 70

Let's proceed to step 6:
525 divided by 70 is 7 with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 11617.0
If we subtract 490 from 525, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
350 divided by 70 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 11617.5
The remainder is 0 after subtracting 350 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 70 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11617.5
Subtracting 0 from 0 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.

Going ahead to step 9:
If we divide 0 by 70, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11617.5
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.

The quotient of the division is 11617.5, and the remainder is 0.0.
