We look at the division of 40072034 by 574 
The aim is to understand the frequency of 574 in 40072034.

Advancing to step 1:
When dividing 4 by 574, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 574

Let's proceed to step 2:
When dividing 40 by 574, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 574

Let's proceed to step 3:
574 goes into 400 0 times with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 400 to get 400.
Fetch the next digit (7) from the dividend, attach it to 400 and continue: 4007 / 574

Advancing to step 4:
The number 574 fits into 4007 6 times, leaving a remainder of 563.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 3444 away from 4007, we end up with 563.
Append the next digit (2) from the dividend to 563 and continue with: 5632 / 574

Moving on to step 5:
If we divide 5632 by 574, we get 9 and a remainder of 466.
Use 9 as the next digit of our solution. 
Result so far: 69.0
Deduct 5166 from 5632 and we're left with 466.
Include the next digit (0) from the dividend after 466, then repeat: 4660 / 574

Moving on to step 6:
The number 574 fits into 4660 8 times, leaving a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 698.0
Subtract 4592 from 4660 to get 68.
Take the next digit (3) from the dividend and append it to 68, then repeat: 683 / 574

Step 7:
683 divided by 574 is 1 with a remainder of 109.
Use 1 as the next digit of our solution. 
Result so far: 6981.0
If we subtract 574 from 683, we get 109.
Fetch the next digit (4) from the dividend, attach it to 109 and continue: 1094 / 574

Moving on to step 8:
574 can be fit into 1094 1 times, resulting in a remainder of 520.
The next digit of our result is 1. 
Result so far: 69811.0
Subtract 574 from 1094 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 9:
574 can be fit into 5200 9 times, resulting in a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 69811.9
Deduct 5166 from 5200 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
574 goes into 340 0 times with a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 69811.9
If we take 0 away from 340, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 11:
3400 divided by 574 is 5 with a remainder of 530.
Use 5 as the next digit of our solution. 
Result so far: 69811.905
If we subtract 2870 from 3400, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 12:
574 can be fit into 5300 9 times, resulting in a remainder of 134.
The next digit of our result is 9. 
Result so far: 69811.9059
If we subtract 5166 from 5300, we 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.

Let's proceed to step 13:
The number 574 fits into 1340 2 times, leaving a remainder of 192.
Record the quotient 2 as the next digit in the result. 
Result so far: 69811.90592
If we subtract 1148 from 1340, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 14:
574 can be fit into 1920 3 times, resulting in a remainder of 198.
Use 3 as the next digit of our solution. 
Result so far: 69811.905923
Subtracting 1722 from 1920 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 15:
574 goes into 1980 3 times with a remainder of 258.
The next digit of our result is 3. 
Result so far: 69811.9059233
Deduct 1722 from 1980 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

The final result is 69811.9059233 with a remainder of 2.58e-06.
