18213160 ÷ 74 
The aim is to understand the frequency of 74 in 18213160.

Step 1:
1 divided by 74 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 74

Going ahead to step 2:
74 goes into 18 0 times with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 74

Advancing to step 3:
When dividing 182 by 74, we get 2 with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 148 from 182 leaves us with 34.
Fetch the next digit (1) from the dividend, attach it to 34 and continue: 341 / 74

Step 4:
If we divide 341 by 74, we get 4 and a remainder of 45.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
The remainder is 45 after subtracting 296 from 341.
Grab the next digit (3) from the dividend, add it to 45, then carry on: 453 / 74

Advancing to step 5:
453 divided by 74 is 6 with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 246.0
Deduct 444 from 453 and we're left with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 74

Let's proceed to step 6:
74 can be fit into 91 1 times, resulting in a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 2461.0
The remainder is 17 after subtracting 74 from 91.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 74

Going ahead to step 7:
74 goes into 176 2 times with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 24612.0
If we subtract 148 from 176, we get 28.
Append the next digit (0) from the dividend to 28 and continue with: 280 / 74

Advancing to step 8:
280 divided by 74 is 3 with a remainder of 58.
The next digit of our result is 3. 
Result so far: 246123.0
If we take 222 away from 280, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 9:
The number 74 fits into 580 7 times, leaving a remainder of 62.
The next digit of our result is 7. 
Result so far: 246123.7
The remainder is 62 after subtracting 518 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 10:
If we divide 620 by 74, we get 8 and a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 246123.78
The remainder is 28 after subtracting 592 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
74 can be fit into 280 3 times, resulting in a remainder of 58.
Write down 3 as next digit of the result. 
Result so far: 246123.783
If we subtract 222 from 280, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 12:
74 goes into 580 7 times with a remainder of 62.
The number 7 becomes the next digit in our result. 
Result so far: 246123.7837
If we take 518 away from 580, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 13:
The number 74 fits into 620 8 times, leaving a remainder of 28.
The next digit of our result is 8. 
Result so far: 246123.78378
If we take 592 away from 620, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 14:
280 divided by 74 is 3 with a remainder of 58.
Use 3 as the next digit of our solution. 
Result so far: 246123.783783
Deduct 222 from 280 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 15:
The number 74 fits into 580 7 times, leaving a remainder of 62.
The next digit of our result is 7. 
Result so far: 246123.7837837
The remainder is 62 after subtracting 518 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 16:
620 divided by 74 is 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 246123.78378378
Subtract 592 from 620 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

In conclusion, the division gives 246123.78378378 with a balance of 2.8e-08.
