91713486 ÷ 429 
The aim is to understand the frequency of 429 in 91713486.

On to step 1:
429 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 429

Moving on to step 2:
429 goes into 91 0 times with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Include the next digit (7) from the dividend after 91, then repeat: 917 / 429

Moving on to step 3:
The number 429 fits into 917 2 times, leaving a remainder of 59.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 858 from 917 and we're left with 59.
Include the next digit (1) from the dividend after 59, then repeat: 591 / 429

Let's proceed to step 4:
429 can be fit into 591 1 times, resulting in a remainder of 162.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 429 from 591 to get 162.
Take the next digit (3) from the dividend and append it to 162, then repeat: 1623 / 429

Moving on to step 5:
429 can be fit into 1623 3 times, resulting in a remainder of 336.
Record the quotient 3 as the next digit in the result. 
Result so far: 213.0
Subtracting 1287 from 1623 leaves us with 336.
Fetch the next digit (4) from the dividend, attach it to 336 and continue: 3364 / 429

Let's proceed to step 6:
The number 429 fits into 3364 7 times, leaving a remainder of 361.
The next digit of our result is 7. 
Result so far: 2137.0
Subtract 3003 from 3364 to get 361.
Take the next digit (8) from the dividend and append it to 361, then repeat: 3618 / 429

Moving on to step 7:
429 goes into 3618 8 times with a remainder of 186.
Use 8 as the next digit of our solution. 
Result so far: 21378.0
The remainder is 186 after subtracting 3432 from 3618.
Include the next digit (6) from the dividend after 186, then repeat: 1866 / 429

On to step 8:
If we divide 1866 by 429, we get 4 and a remainder of 150.
The number 4 becomes the next digit in our result. 
Result so far: 213784.0
The remainder is 150 after subtracting 1716 from 1866.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 9:
1500 divided by 429 is 3 with a remainder of 213.
The number 3 becomes the next digit in our result. 
Result so far: 213784.3
If we take 1287 away from 1500, we end up with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Step 10:
429 can be fit into 2130 4 times, resulting in a remainder of 414.
Record the quotient 4 as the next digit in the result. 
Result so far: 213784.34
If we take 1716 away from 2130, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Moving on to step 11:
429 can be fit into 4140 9 times, resulting in a remainder of 279.
Write down 9 as next digit of the result. 
Result so far: 213784.349
Subtracting 3861 from 4140 leaves us with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Going ahead to step 12:
429 can be fit into 2790 6 times, resulting in a remainder of 216.
Record the quotient 6 as the next digit in the result. 
Result so far: 213784.3496
The remainder is 216 after subtracting 2574 from 2790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 13:
If we divide 2160 by 429, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 213784.34965
Deduct 2145 from 2160 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 14:
150 divided by 429 is 0 with a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 213784.34965
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 15:
The number 429 fits into 1500 3 times, leaving a remainder of 213.
The next digit of our result is 3. 
Result so far: 213784.3496503
Deduct 1287 from 1500 and we're left with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Step 16:
429 can be fit into 2130 4 times, resulting in a remainder of 414.
Put 4 as the next digit of the answer. 
Result so far: 213784.34965034
The remainder is 414 after subtracting 1716 from 2130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

The quotient of the division is 213784.34965034, and the remainder is 4.14e-07.
