401212 ÷ 74 
The aim is to understand the frequency of 74 in 401212.

Let's proceed to step 1:
If we divide 4 by 74, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 74

Let's proceed to step 2:
74 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 74

On to step 3:
74 can be fit into 401 5 times, resulting in a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 370 from 401 to get 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 74

On to step 4:
74 goes into 312 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 54.0
Subtract 296 from 312 to get 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 74

Step 5:
74 goes into 161 2 times with a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 542.0
If we take 148 away from 161, we end up with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 74

Going ahead to step 6:
74 can be fit into 132 1 times, resulting in a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 5421.0
If we take 74 away from 132, 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.

Moving on to step 7:
If we divide 580 by 74, we get 7 and a remainder of 62.
The number 7 becomes the next digit in our result. 
Result so far: 5421.7
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.

Moving on to step 8:
When dividing 620 by 74, we get 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 5421.78
If we subtract 592 from 620, we 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.

On to step 9:
280 divided by 74 is 3 with a remainder of 58.
Write down 3 as next digit of the result. 
Result so far: 5421.783
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.

Advancing to step 10:
74 can be fit into 580 7 times, resulting in a remainder of 62.
The number 7 becomes the next digit in our result. 
Result so far: 5421.7837
Deduct 518 from 580 and we're left 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.

Going ahead to step 11:
74 goes into 620 8 times with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 5421.78378
Deduct 592 from 620 and we're left 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.

Let's proceed to step 12:
The number 74 fits into 280 3 times, leaving a remainder of 58.
Write down 3 as next digit of the result. 
Result so far: 5421.783783
Subtract 222 from 280 to 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.

Moving on to step 13:
When dividing 580 by 74, we get 7 with a remainder of 62.
Put 7 as the next digit of the answer. 
Result so far: 5421.7837837
If we subtract 518 from 580, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 14:
74 can be fit into 620 8 times, resulting in a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 5421.78378378
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.

Our division results in 5421.78378378 with a remaining 2.8e-08.
