We're dividing 429091 by 670 
The aim is to understand the frequency of 670 in 429091.

Let's proceed to step 1:
670 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 670

Moving on to step 2:
If we divide 42 by 670, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 670

Let's proceed to step 3:
670 goes into 429 0 times with a remainder of 429.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 429, we get 429.
Take the next digit (0) from the dividend and append it to 429, then repeat: 4290 / 670

Let's proceed to step 4:
When dividing 4290 by 670, we get 6 with a remainder of 270.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 4020 from 4290 and we're left with 270.
Take the next digit (9) from the dividend and append it to 270, then repeat: 2709 / 670

Let's proceed to step 5:
2709 divided by 670 is 4 with a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Deduct 2680 from 2709 and we're left with 29.
Include the next digit (1) from the dividend after 29, then repeat: 291 / 670

Moving on to step 6:
The number 670 fits into 291 0 times, leaving a remainder of 291.
Put 0 as the next digit of the answer. 
Result so far: 640.0
If we subtract 0 from 291, we get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Moving on to step 7:
2910 divided by 670 is 4 with a remainder of 230.
Put 4 as the next digit of the answer. 
Result so far: 640.4
The remainder is 230 after subtracting 2680 from 2910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 8:
670 can be fit into 2300 3 times, resulting in a remainder of 290.
The number 3 becomes the next digit in our result. 
Result so far: 640.43
Subtracting 2010 from 2300 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 9:
2900 divided by 670 is 4 with a remainder of 220.
Write down 4 as next digit of the result. 
Result so far: 640.434
The remainder is 220 after subtracting 2680 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 10:
670 can be fit into 2200 3 times, resulting in a remainder of 190.
The next digit of our result is 3. 
Result so far: 640.4343
If we subtract 2010 from 2200, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 11:
If we divide 1900 by 670, we get 2 and a remainder of 560.
The next digit of our result is 2. 
Result so far: 640.43432
If we take 1340 away from 1900, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 12:
5600 divided by 670 is 8 with a remainder of 240.
The number 8 becomes the next digit in our result. 
Result so far: 640.434328
The remainder is 240 after subtracting 5360 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 13:
When dividing 2400 by 670, we get 3 with a remainder of 390.
Put 3 as the next digit of the answer. 
Result so far: 640.4343283
Subtract 2010 from 2400 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 14:
670 can be fit into 3900 5 times, resulting in a remainder of 550.
The number 5 becomes the next digit in our result. 
Result so far: 640.43432835
Subtract 3350 from 3900 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

After the division, we end up with 640.43432835 and a remainder of 5.5e-07.
