We look at the division of 45105889 by 74 
The aim is to understand the frequency of 74 in 45105889.

On to step 1:
4 divided by 74 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 74

Step 2:
74 can be fit into 45 0 times, resulting in a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Append the next digit (1) from the dividend to 45 and continue with: 451 / 74

Let's proceed to step 3:
74 goes into 451 6 times with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 444 from 451 leaves us with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 74

Step 4:
If we divide 70 by 74, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 60.0
If we subtract 0 from 70, we get 70.
Take the next digit (5) from the dividend and append it to 70, then repeat: 705 / 74

On to step 5:
When dividing 705 by 74, we get 9 with a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 609.0
Subtracting 666 from 705 leaves us with 39.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 74

Going ahead to step 6:
If we divide 398 by 74, we get 5 and a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 6095.0
If we take 370 away from 398, we end up with 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 74

Moving on to step 7:
74 can be fit into 288 3 times, resulting in a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 60953.0
If we take 222 away from 288, we end up with 66.
Include the next digit (9) from the dividend after 66, then repeat: 669 / 74

On to step 8:
74 goes into 669 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 609539.0
Deduct 666 from 669 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
30 divided by 74 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 609539.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
74 goes into 300 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 609539.04
If we take 296 away from 300, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
If we divide 40 by 74, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 609539.04
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
74 goes into 400 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 609539.0405
If we subtract 370 from 400, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
74 goes into 300 4 times with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 609539.04054
The remainder is 4 after subtracting 296 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
74 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 609539.04054
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 15:
74 goes into 400 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 609539.0405405
If we subtract 370 from 400, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 16:
The number 74 fits into 300 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 609539.04054054
Subtracting 296 from 300 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 609539.04054054 with a remaining 4e-09.
