5074343 ÷ 691 
The aim is to understand the frequency of 691 in 5074343.

Step 1:
691 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 691

Let's proceed to step 2:
691 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Fetch the next digit (7) from the dividend, attach it to 50 and continue: 507 / 691

Going ahead to step 3:
The number 691 fits into 507 0 times, leaving a remainder of 507.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 507 to get 507.
Take the next digit (4) from the dividend and append it to 507, then repeat: 5074 / 691

Moving on to step 4:
691 goes into 5074 7 times with a remainder of 237.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 4837 from 5074 and we're left with 237.
Grab the next digit (3) from the dividend, add it to 237, then carry on: 2373 / 691

Let's proceed to step 5:
When dividing 2373 by 691, we get 3 with a remainder of 300.
The next digit of our result is 3. 
Result so far: 73.0
If we subtract 2073 from 2373, we get 300.
Append the next digit (4) from the dividend to 300 and continue with: 3004 / 691

Moving on to step 6:
When dividing 3004 by 691, we get 4 with a remainder of 240.
The number 4 becomes the next digit in our result. 
Result so far: 734.0
Subtract 2764 from 3004 to get 240.
Bring next digit (3) of the dividend behind the 240 and repeat the process: 2403 / 691

Step 7:
2403 divided by 691 is 3 with a remainder of 330.
The next digit of our result is 3. 
Result so far: 7343.0
The remainder is 330 after subtracting 2073 from 2403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 8:
691 can be fit into 3300 4 times, resulting in a remainder of 536.
Put 4 as the next digit of the answer. 
Result so far: 7343.4
If we subtract 2764 from 3300, we get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Advancing to step 9:
When dividing 5360 by 691, we get 7 with a remainder of 523.
Use 7 as the next digit of our solution. 
Result so far: 7343.47
If we take 4837 away from 5360, we end up with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Let's proceed to step 10:
5230 divided by 691 is 7 with a remainder of 393.
The next digit of our result is 7. 
Result so far: 7343.477
Subtract 4837 from 5230 to get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Our division results in 7343.477 with a remaining 0.0393.
