We look at the division of 56151962 by 429 
The aim is to understand the frequency of 429 in 56151962.

Advancing to step 1:
If we divide 5 by 429, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 429

Moving on to step 2:
If we divide 56 by 429, we get 0 and a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Include the next digit (1) from the dividend after 56, then repeat: 561 / 429

Let's proceed to step 3:
When dividing 561 by 429, we get 1 with a remainder of 132.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 429 from 561 and we're left with 132.
Bring next digit (5) of the dividend behind the 132 and repeat the process: 1325 / 429

On to step 4:
When dividing 1325 by 429, we get 3 with a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 1287 from 1325 and we're left with 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 429

On to step 5:
429 goes into 381 0 times with a remainder of 381.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
If we take 0 away from 381, we end up with 381.
Take the next digit (9) from the dividend and append it to 381, then repeat: 3819 / 429

Let's proceed to step 6:
If we divide 3819 by 429, we get 8 and a remainder of 387.
The number 8 becomes the next digit in our result. 
Result so far: 1308.0
If we subtract 3432 from 3819, we get 387.
Take the next digit (6) from the dividend and append it to 387, then repeat: 3876 / 429

Step 7:
When dividing 3876 by 429, we get 9 with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 13089.0
The remainder is 15 after subtracting 3861 from 3876.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 429

Step 8:
When dividing 152 by 429, we get 0 with a remainder of 152.
The number 0 becomes the next digit in our result. 
Result so far: 130890.0
If we take 0 away from 152, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 9:
The number 429 fits into 1520 3 times, leaving a remainder of 233.
Use 3 as the next digit of our solution. 
Result so far: 130890.3
Subtract 1287 from 1520 to get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Moving on to step 10:
When dividing 2330 by 429, we get 5 with a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 130890.35
If we subtract 2145 from 2330, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 11:
If we divide 1850 by 429, we get 4 and a remainder of 134.
Put 4 as the next digit of the answer. 
Result so far: 130890.354
Subtract 1716 from 1850 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 12:
If we divide 1340 by 429, we get 3 and a remainder of 53.
The next digit of our result is 3. 
Result so far: 130890.3543
Subtract 1287 from 1340 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 13:
429 goes into 530 1 times with a remainder of 101.
The number 1 becomes the next digit in our result. 
Result so far: 130890.35431
If we take 429 away from 530, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 14:
429 goes into 1010 2 times with a remainder of 152.
The next digit of our result is 2. 
Result so far: 130890.354312
If we subtract 858 from 1010, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 15:
429 goes into 1520 3 times with a remainder of 233.
Write down 3 as next digit of the result. 
Result so far: 130890.3543123
If we subtract 1287 from 1520, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Going ahead to step 16:
429 can be fit into 2330 5 times, resulting in a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 130890.35431235
If we subtract 2145 from 2330, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

The final outcome is 130890.35431235, with a leftover of 1.85e-07.
