31620293 divided by 429 
The aim is to understand the frequency of 429 in 31620293.

Let's proceed to step 1:
If we divide 3 by 429, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 429

Moving on to step 2:
If we divide 31 by 429, we get 0 and a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Include the next digit (6) from the dividend after 31, then repeat: 316 / 429

Let's proceed to step 3:
429 can be fit into 316 0 times, resulting in a remainder of 316.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 316 to get 316.
Grab the next digit (2) from the dividend, add it to 316, then carry on: 3162 / 429

Let's proceed to step 4:
3162 divided by 429 is 7 with a remainder of 159.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 3003 from 3162 and we're left with 159.
Bring next digit (0) of the dividend behind the 159 and repeat the process: 1590 / 429

Step 5:
429 goes into 1590 3 times with a remainder of 303.
Write down 3 as next digit of the result. 
Result so far: 73.0
Deduct 1287 from 1590 and we're left with 303.
Append the next digit (2) from the dividend to 303 and continue with: 3032 / 429

Advancing to step 6:
The number 429 fits into 3032 7 times, leaving a remainder of 29.
The next digit of our result is 7. 
Result so far: 737.0
If we subtract 3003 from 3032, we get 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 429

Step 7:
429 goes into 299 0 times with a remainder of 299.
The number 0 becomes the next digit in our result. 
Result so far: 7370.0
If we take 0 away from 299, we end up with 299.
Include the next digit (3) from the dividend after 299, then repeat: 2993 / 429

On to step 8:
If we divide 2993 by 429, we get 6 and a remainder of 419.
Record the quotient 6 as the next digit in the result. 
Result so far: 73706.0
Deduct 2574 from 2993 and we're left with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Step 9:
When dividing 4190 by 429, we get 9 with a remainder of 329.
Use 9 as the next digit of our solution. 
Result so far: 73706.9
If we take 3861 away from 4190, we end up with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Step 10:
If we divide 3290 by 429, we get 7 and a remainder of 287.
Put 7 as the next digit of the answer. 
Result so far: 73706.97
Subtracting 3003 from 3290 leaves us with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Let's proceed to step 11:
The number 429 fits into 2870 6 times, leaving a remainder of 296.
Record the quotient 6 as the next digit in the result. 
Result so far: 73706.976
Subtracting 2574 from 2870 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 12:
2960 divided by 429 is 6 with a remainder of 386.
The number 6 becomes the next digit in our result. 
Result so far: 73706.9766
Subtracting 2574 from 2960 leaves us with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

In conclusion, the division gives 73706.9766 with a balance of 0.00386.
