We divide 606906 by 31
The aim is to understand the frequency of 31 in 606906.

Let's proceed to step 1:
31 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 31

Let's proceed to step 2:
When dividing 60 by 31, we get 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 31 from 60 and we're left with 29.
Grab the next digit (6) from the dividend, add it to 29, then carry on: 296 / 31

Going ahead to step 3:
When dividing 296 by 31, we get 9 with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we subtract 279 from 296, we get 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 31

Going ahead to step 4:
If we divide 179 by 31, we get 5 and a remainder of 24.
Record the quotient 5 as the next digit in the result. 
Result so far: 195.0
Subtract 155 from 179 to get 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 31

Step 5:
31 goes into 240 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 1957.0
Subtract 217 from 240 to get 23.
Append the next digit (6) from the dividend to 23 and continue with: 236 / 31

Going ahead to step 6:
When dividing 236 by 31, we get 7 with a remainder of 19.
The next digit of our result is 7. 
Result so far: 19577.0
Deduct 217 from 236 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
190 divided by 31 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 19577.6
Subtracting 186 from 190 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
31 can be fit into 40 1 times, resulting in a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 19577.61
If we take 31 away from 40, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
The number 31 fits into 90 2 times, leaving a remainder of 28.
The next digit of our result is 2. 
Result so far: 19577.612
Subtract 62 from 90 to 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.

Going ahead to step 10:
The number 31 fits into 280 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 19577.6129
Deduct 279 from 280 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
If we divide 10 by 31, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 19577.6129
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
31 goes into 100 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 19577.612903
Subtracting 93 from 100 leaves us 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 13:
When dividing 70 by 31, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 19577.6129032
Deduct 62 from 70 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
When dividing 80 by 31, we get 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 19577.61290322
Subtracting 62 from 80 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 19577.61290322 with a remainder of 1.8e-08.
