233721 ÷ 74 
The aim is to understand the frequency of 74 in 233721.

Step 1:
When dividing 2 by 74, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 74

Advancing to step 2:
If we divide 23 by 74, we get 0 and a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Fetch the next digit (3) from the dividend, attach it to 23 and continue: 233 / 74

Going ahead to step 3:
When dividing 233 by 74, we get 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 222 from 233 leaves us with 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 74

Moving on to step 4:
The number 74 fits into 117 1 times, leaving a remainder of 43.
The next digit of our result is 1. 
Result so far: 31.0
Subtracting 74 from 117 leaves us with 43.
Grab the next digit (2) from the dividend, add it to 43, then carry on: 432 / 74

Advancing to step 5:
432 divided by 74 is 5 with a remainder of 62.
Write down 5 as next digit of the result. 
Result so far: 315.0
Subtracting 370 from 432 leaves us with 62.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 74

Going ahead to step 6:
621 divided by 74 is 8 with a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 3158.0
Subtracting 592 from 621 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
If we divide 290 by 74, we get 3 and a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 3158.3
Subtracting 222 from 290 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 8:
The number 74 fits into 680 9 times, leaving a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 3158.39
If we take 666 away from 680, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
When dividing 140 by 74, we get 1 with a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 3158.391
Subtract 74 from 140 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
660 divided by 74 is 8 with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 3158.3918
Deduct 592 from 660 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 11:
74 goes into 680 9 times with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 3158.39189
If we subtract 666 from 680, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 12:
140 divided by 74 is 1 with a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 3158.391891
Deduct 74 from 140 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 13:
74 can be fit into 660 8 times, resulting in a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 3158.3918918
Deduct 592 from 660 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 14:
74 can be fit into 680 9 times, resulting in a remainder of 14.
The next digit of our result is 9. 
Result so far: 3158.39189189
If we take 666 away from 680, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 3158.39189189 with a remaining 1.4e-08.
