221566 ÷ 74 
The aim is to understand the frequency of 74 in 221566.

Step 1:
The number 74 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 74

On to step 2:
74 goes into 22 0 times with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 74

On to step 3:
The number 74 fits into 221 2 times, leaving a remainder of 73.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 148 from 221 leaves us with 73.
Grab the next digit (5) from the dividend, add it to 73, then carry on: 735 / 74

Step 4:
74 can be fit into 735 9 times, resulting in a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we take 666 away from 735, we end up with 69.
Fetch the next digit (6) from the dividend, attach it to 69 and continue: 696 / 74

Step 5:
74 can be fit into 696 9 times, resulting in a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 299.0
Subtract 666 from 696 to get 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 74

Advancing to step 6:
If we divide 306 by 74, we get 4 and a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 2994.0
Subtract 296 from 306 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
If we divide 100 by 74, we get 1 and a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 2994.1
The remainder is 26 after subtracting 74 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
The number 74 fits into 260 3 times, leaving a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 2994.13
Subtracting 222 from 260 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
If we divide 380 by 74, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 2994.135
Deduct 370 from 380 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
The number 74 fits into 100 1 times, leaving a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 2994.1351
Subtract 74 from 100 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 11:
260 divided by 74 is 3 with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 2994.13513
Deduct 222 from 260 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
The number 74 fits into 380 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 2994.135135
If we subtract 370 from 380, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
74 goes into 100 1 times with a remainder of 26.
The next digit of our result is 1. 
Result so far: 2994.1351351
Subtract 74 from 100 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
74 goes into 260 3 times with a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 2994.13513513
If we subtract 222 from 260, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 2994.13513513, and the remainder is 3.8e-08.
