Let's divide 401688 by 74
The aim is to understand the frequency of 74 in 401688.

Going ahead to step 1:
4 divided by 74 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 74

Let's proceed to step 2:
74 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 74

Let's proceed to step 3:
The number 74 fits into 401 5 times, leaving a remainder of 31.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 370 from 401 and we're left with 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 74

On to step 4:
If we divide 316 by 74, we get 4 and a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
The remainder is 20 after subtracting 296 from 316.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 74

Advancing to step 5:
When dividing 208 by 74, we get 2 with a remainder of 60.
The next digit of our result is 2. 
Result so far: 542.0
The remainder is 60 after subtracting 148 from 208.
Fetch the next digit (8) from the dividend, attach it to 60 and continue: 608 / 74

Going ahead to step 6:
If we divide 608 by 74, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 5428.0
Subtract 592 from 608 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
160 divided by 74 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 5428.2
If we subtract 148 from 160, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
If we divide 120 by 74, we get 1 and a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 5428.21
Subtract 74 from 120 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 9:
The number 74 fits into 460 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 5428.216
Deduct 444 from 460 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
160 divided by 74 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 5428.2162
If we subtract 148 from 160, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
The number 74 fits into 120 1 times, leaving a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 5428.21621
If we take 74 away from 120, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
If we divide 460 by 74, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 5428.216216
The remainder is 16 after subtracting 444 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
74 can be fit into 160 2 times, resulting in a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 5428.2162162
If we take 148 away from 160, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
The number 74 fits into 120 1 times, leaving a remainder of 46.
Record the quotient 1 as the next digit in the result. 
Result so far: 5428.21621621
Subtract 74 from 120 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

After the division, we end up with 5428.21621621 and a remainder of 4.6e-08.
