Let's divide 43458920 by 574
The aim is to understand the frequency of 574 in 43458920.

Going ahead to step 1:
574 goes into 4 0 times with 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.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 574

On to step 2:
574 goes into 43 0 times with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Bring next digit (4) of the dividend behind the 43 and repeat the process: 434 / 574

Let's proceed to step 3:
When dividing 434 by 574, we get 0 with a remainder of 434.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 434 and we're left with 434.
Bring next digit (5) of the dividend behind the 434 and repeat the process: 4345 / 574

Moving on to step 4:
574 can be fit into 4345 7 times, resulting in a remainder of 327.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 4018 from 4345, we get 327.
Append the next digit (8) from the dividend to 327 and continue with: 3278 / 574

Step 5:
If we divide 3278 by 574, we get 5 and a remainder of 408.
Use 5 as the next digit of our solution. 
Result so far: 75.0
Subtracting 2870 from 3278 leaves us with 408.
Bring next digit (9) of the dividend behind the 408 and repeat the process: 4089 / 574

Advancing to step 6:
574 goes into 4089 7 times with a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 757.0
Subtract 4018 from 4089 to get 71.
Take the next digit (2) from the dividend and append it to 71, then repeat: 712 / 574

Let's proceed to step 7:
When dividing 712 by 574, we get 1 with a remainder of 138.
Put 1 as the next digit of the answer. 
Result so far: 7571.0
If we take 574 away from 712, we end up with 138.
Append the next digit (0) from the dividend to 138 and continue with: 1380 / 574

Step 8:
If we divide 1380 by 574, we get 2 and a remainder of 232.
Use 2 as the next digit of our solution. 
Result so far: 75712.0
The remainder is 232 after subtracting 1148 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 9:
574 goes into 2320 4 times with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 75712.4
Subtract 2296 from 2320 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
574 goes into 240 0 times with a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 75712.4
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 11:
574 goes into 2400 4 times with a remainder of 104.
Record the quotient 4 as the next digit in the result. 
Result so far: 75712.404
Deduct 2296 from 2400 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 12:
1040 divided by 574 is 1 with a remainder of 466.
Use 1 as the next digit of our solution. 
Result so far: 75712.4041
If we take 574 away from 1040, we end up with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Advancing to step 13:
574 can be fit into 4660 8 times, resulting in a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 75712.40418
Subtract 4592 from 4660 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 14:
680 divided by 574 is 1 with a remainder of 106.
Write down 1 as next digit of the result. 
Result so far: 75712.404181
Subtract 574 from 680 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 15:
574 goes into 1060 1 times with a remainder of 486.
Put 1 as the next digit of the answer. 
Result so far: 75712.4041811
Subtracting 574 from 1060 leaves us with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Our division results in 75712.4041811 with a remaining 4.86e-06.
