743594 ÷ 74 
The aim is to understand the frequency of 74 in 743594.

On to step 1:
When dividing 7 by 74, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 74

On to step 2:
74 divided by 74 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 74 from 74 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 74

Step 3:
3 divided by 74 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 3 to get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 74

Going ahead to step 4:
74 goes into 35 0 times with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtract 0 from 35 to get 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 74

Step 5:
When dividing 359 by 74, we get 4 with a remainder of 63.
Put 4 as the next digit of the answer. 
Result so far: 1004.0
The remainder is 63 after subtracting 296 from 359.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 74

Going ahead to step 6:
If we divide 634 by 74, we get 8 and a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 10048.0
Subtract 592 from 634 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
420 divided by 74 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 10048.5
Subtracting 370 from 420 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
74 goes into 500 6 times with a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 10048.56
The remainder is 56 after subtracting 444 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 9:
74 can be fit into 560 7 times, resulting in a remainder of 42.
The next digit of our result is 7. 
Result so far: 10048.567
Deduct 518 from 560 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
When dividing 420 by 74, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 10048.5675
If we take 370 away from 420, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
When dividing 500 by 74, we get 6 with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 10048.56756
The remainder is 56 after subtracting 444 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 12:
74 can be fit into 560 7 times, resulting in a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 10048.567567
Subtract 518 from 560 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
The number 74 fits into 420 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 10048.5675675
Subtract 370 from 420 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
The number 74 fits into 500 6 times, leaving a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 10048.56756756
If we take 444 away from 500, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 10048.56756756, with a leftover of 5.6e-08.
