We're dividing 70661926 by 429 
The aim is to understand the frequency of 429 in 70661926.

On to step 1:
429 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 429

Advancing to step 2:
70 divided by 429 is 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Take the next digit (6) from the dividend and append it to 70, then repeat: 706 / 429

Advancing to step 3:
706 divided by 429 is 1 with a remainder of 277.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 429 away from 706, we end up with 277.
Fetch the next digit (6) from the dividend, attach it to 277 and continue: 2776 / 429

Moving on to step 4:
2776 divided by 429 is 6 with a remainder of 202.
The next digit of our result is 6. 
Result so far: 16.0
If we take 2574 away from 2776, we end up with 202.
Grab the next digit (1) from the dividend, add it to 202, then carry on: 2021 / 429

Let's proceed to step 5:
If we divide 2021 by 429, we get 4 and a remainder of 305.
The number 4 becomes the next digit in our result. 
Result so far: 164.0
Subtract 1716 from 2021 to get 305.
Bring next digit (9) of the dividend behind the 305 and repeat the process: 3059 / 429

Moving on to step 6:
The number 429 fits into 3059 7 times, leaving a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 1647.0
Deduct 3003 from 3059 and we're left with 56.
Take the next digit (2) from the dividend and append it to 56, then repeat: 562 / 429

Let's proceed to step 7:
If we divide 562 by 429, we get 1 and a remainder of 133.
Put 1 as the next digit of the answer. 
Result so far: 16471.0
Subtracting 429 from 562 leaves us with 133.
Include the next digit (6) from the dividend after 133, then repeat: 1336 / 429

Going ahead to step 8:
429 can be fit into 1336 3 times, resulting in a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 164713.0
The remainder is 49 after subtracting 1287 from 1336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
When dividing 490 by 429, we get 1 with a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 164713.1
If we take 429 away from 490, we end up 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.

Let's proceed to step 10:
When dividing 610 by 429, we get 1 with a remainder of 181.
Record the quotient 1 as the next digit in the result. 
Result so far: 164713.11
The remainder is 181 after subtracting 429 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

The final outcome is 164713.11, with a leftover of 0.181.
