We're dividing 18935225 by 429 
The aim is to understand the frequency of 429 in 18935225.

Advancing to step 1:
1 divided by 429 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 429

Going ahead to step 2:
18 divided by 429 is 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 429

On to step 3:
The number 429 fits into 189 0 times, leaving a remainder of 189.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 189, we get 189.
Grab the next digit (3) from the dividend, add it to 189, then carry on: 1893 / 429

Let's proceed to step 4:
If we divide 1893 by 429, we get 4 and a remainder of 177.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 1716 from 1893 and we're left with 177.
Fetch the next digit (5) from the dividend, attach it to 177 and continue: 1775 / 429

Step 5:
When dividing 1775 by 429, we get 4 with a remainder of 59.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
The remainder is 59 after subtracting 1716 from 1775.
Append the next digit (2) from the dividend to 59 and continue with: 592 / 429

Let's proceed to step 6:
When dividing 592 by 429, we get 1 with a remainder of 163.
Record the quotient 1 as the next digit in the result. 
Result so far: 441.0
Subtracting 429 from 592 leaves us with 163.
Bring next digit (2) of the dividend behind the 163 and repeat the process: 1632 / 429

Advancing to step 7:
The number 429 fits into 1632 3 times, leaving a remainder of 345.
Write down 3 as next digit of the result. 
Result so far: 4413.0
Subtract 1287 from 1632 to get 345.
Fetch the next digit (5) from the dividend, attach it to 345 and continue: 3455 / 429

Let's proceed to step 8:
429 goes into 3455 8 times with a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 44138.0
The remainder is 23 after subtracting 3432 from 3455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 9:
429 goes into 230 0 times with a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 44138.0
Deduct 0 from 230 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 10:
If we divide 2300 by 429, we get 5 and a remainder of 155.
Put 5 as the next digit of the answer. 
Result so far: 44138.05
Subtracting 2145 from 2300 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 11:
The number 429 fits into 1550 3 times, leaving a remainder of 263.
Write down 3 as next digit of the result. 
Result so far: 44138.053
Subtracting 1287 from 1550 leaves us with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Step 12:
When dividing 2630 by 429, we get 6 with a remainder of 56.
The next digit of our result is 6. 
Result so far: 44138.0536
If we take 2574 away from 2630, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 13:
429 goes into 560 1 times with a remainder of 131.
The next digit of our result is 1. 
Result so far: 44138.05361
Deduct 429 from 560 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

On to step 14:
1310 divided by 429 is 3 with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 44138.053613
If we subtract 1287 from 1310, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 15:
429 goes into 230 0 times with a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 44138.053613
Subtracting 0 from 230 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 16:
429 goes into 2300 5 times with a remainder of 155.
Record the quotient 5 as the next digit in the result. 
Result so far: 44138.05361305
Subtracting 2145 from 2300 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

The final outcome is 44138.05361305, with a leftover of 1.55e-07.
