31475420 ÷ 604 
The aim is to understand the frequency of 604 in 31475420.

Let's proceed to step 1:
604 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 604

Moving on to step 2:
604 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 604

Step 3:
314 divided by 604 is 0 with a remainder of 314.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 314 and we're left with 314.
Grab the next digit (7) from the dividend, add it to 314, then carry on: 3147 / 604

Advancing to step 4:
604 goes into 3147 5 times with a remainder of 127.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 3020 from 3147 and we're left with 127.
Take the next digit (5) from the dividend and append it to 127, then repeat: 1275 / 604

Moving on to step 5:
1275 divided by 604 is 2 with a remainder of 67.
The next digit of our result is 2. 
Result so far: 52.0
The remainder is 67 after subtracting 1208 from 1275.
Append the next digit (4) from the dividend to 67 and continue with: 674 / 604

Let's proceed to step 6:
674 divided by 604 is 1 with a remainder of 70.
The next digit of our result is 1. 
Result so far: 521.0
The remainder is 70 after subtracting 604 from 674.
Append the next digit (2) from the dividend to 70 and continue with: 702 / 604

Advancing to step 7:
When dividing 702 by 604, we get 1 with a remainder of 98.
The number 1 becomes the next digit in our result. 
Result so far: 5211.0
If we take 604 away from 702, we end up with 98.
Grab the next digit (0) from the dividend, add it to 98, then carry on: 980 / 604

Let's proceed to step 8:
When dividing 980 by 604, we get 1 with a remainder of 376.
The next digit of our result is 1. 
Result so far: 52111.0
Deduct 604 from 980 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 9:
The number 604 fits into 3760 6 times, leaving a remainder of 136.
The next digit of our result is 6. 
Result so far: 52111.6
If we take 3624 away from 3760, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 10:
604 can be fit into 1360 2 times, resulting in a remainder of 152.
Use 2 as the next digit of our solution. 
Result so far: 52111.62
Deduct 1208 from 1360 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 11:
The number 604 fits into 1520 2 times, leaving a remainder of 312.
Put 2 as the next digit of the answer. 
Result so far: 52111.622
Deduct 1208 from 1520 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

In conclusion, the division gives 52111.622 with a balance of 0.0312.
