We divide 607668 by 31
The aim is to understand the frequency of 31 in 607668.

Step 1:
31 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 31

Moving on to step 2:
If we divide 60 by 31, we get 1 and a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 31 from 60 to get 29.
Take the next digit (7) from the dividend and append it to 29, then repeat: 297 / 31

Let's proceed to step 3:
31 can be fit into 297 9 times, resulting in a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 279 from 297 and we're left with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 31

On to step 4:
31 can be fit into 186 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 196.0
Subtract 186 from 186 to get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 31

Let's proceed to step 5:
31 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 1960.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 31

On to step 6:
The number 31 fits into 68 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 19602.0
If we take 62 away from 68, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
31 can be fit into 60 1 times, resulting in a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 19602.1
The remainder is 29 after subtracting 31 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 8:
If we divide 290 by 31, we get 9 and a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 19602.19
Subtract 279 from 290 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
31 goes into 110 3 times with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 19602.193
Deduct 93 from 110 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
31 goes into 170 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 19602.1935
Subtracting 155 from 170 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
The number 31 fits into 150 4 times, leaving a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 19602.19354
Deduct 124 from 150 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 12:
The number 31 fits into 260 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 19602.193548
If we subtract 248 from 260, 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.

On to step 13:
31 goes into 120 3 times with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 19602.1935483
Subtracting 93 from 120 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 14:
31 goes into 270 8 times with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 19602.19354838
Deduct 248 from 270 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 19602.19354838 with a remaining 2.2e-08.
