121663 divided by 74 
The aim is to understand the frequency of 74 in 121663.

Step 1:
74 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 74

On to step 2:
12 divided by 74 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 74

On to step 3:
74 goes into 121 1 times with a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 74 from 121 to get 47.
Take the next digit (6) from the dividend and append it to 47, then repeat: 476 / 74

Moving on to step 4:
When dividing 476 by 74, we get 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 444 from 476, we get 32.
Append the next digit (6) from the dividend to 32 and continue with: 326 / 74

Going ahead to step 5:
326 divided by 74 is 4 with a remainder of 30.
The next digit of our result is 4. 
Result so far: 164.0
The remainder is 30 after subtracting 296 from 326.
Fetch the next digit (3) from the dividend, attach it to 30 and continue: 303 / 74

Moving on to step 6:
74 can be fit into 303 4 times, resulting in a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 1644.0
Deduct 296 from 303 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
The number 74 fits into 70 0 times, leaving a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 1644.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
If we divide 700 by 74, we get 9 and a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 1644.09
If we subtract 666 from 700, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
74 goes into 340 4 times with a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 1644.094
The remainder is 44 after subtracting 296 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 10:
440 divided by 74 is 5 with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 1644.0945
Subtract 370 from 440 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 11:
The number 74 fits into 700 9 times, leaving a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 1644.09459
Deduct 666 from 700 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 12:
When dividing 340 by 74, we get 4 with a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 1644.094594
Subtract 296 from 340 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
74 can be fit into 440 5 times, resulting in a remainder of 70.
The next digit of our result is 5. 
Result so far: 1644.0945945
If we take 370 away from 440, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 14:
74 goes into 700 9 times with a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 1644.09459459
If we take 666 away from 700, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 1644.09459459, with a leftover of 3.4e-08.
