We're dividing 42645166 by 74 
The aim is to understand the frequency of 74 in 42645166.

Step 1:
4 divided by 74 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 74

Advancing to step 2:
74 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 74

Going ahead to step 3:
74 goes into 426 5 times with a remainder of 56.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 370 from 426 to get 56.
Grab the next digit (4) from the dividend, add it to 56, then carry on: 564 / 74

Going ahead to step 4:
If we divide 564 by 74, we get 7 and a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
Subtracting 518 from 564 leaves us with 46.
Take the next digit (5) from the dividend and append it to 46, then repeat: 465 / 74

Going ahead to step 5:
The number 74 fits into 465 6 times, leaving a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 576.0
Subtracting 444 from 465 leaves us with 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 74

On to step 6:
74 can be fit into 211 2 times, resulting in a remainder of 63.
Put 2 as the next digit of the answer. 
Result so far: 5762.0
Deduct 148 from 211 and we're left with 63.
Fetch the next digit (6) from the dividend, attach it to 63 and continue: 636 / 74

Going ahead to step 7:
The number 74 fits into 636 8 times, leaving a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 57628.0
Subtract 592 from 636 to get 44.
Append the next digit (6) from the dividend to 44 and continue with: 446 / 74

Advancing to step 8:
74 can be fit into 446 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 576286.0
Subtracting 444 from 446 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
When dividing 20 by 74, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 576286.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
200 divided by 74 is 2 with a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 576286.02
Subtract 148 from 200 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
When dividing 520 by 74, we get 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 576286.027
Deduct 518 from 520 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
The number 74 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 576286.027
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
74 can be fit into 200 2 times, resulting in a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 576286.02702
Subtracting 148 from 200 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 14:
74 can be fit into 520 7 times, resulting in a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 576286.027027
The remainder is 2 after subtracting 518 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 15:
If we divide 20 by 74, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 576286.027027
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 16:
74 can be fit into 200 2 times, resulting in a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 576286.02702702
Deduct 148 from 200 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 576286.02702702 with a remaining 5.2e-08.
