We divide 23475802 by 31
The aim is to understand the frequency of 31 in 23475802.

Going ahead to step 1:
2 divided by 31 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 31

Moving on to step 2:
31 can be fit into 23 0 times, resulting in a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Bring next digit (4) of the dividend behind the 23 and repeat the process: 234 / 31

Let's proceed to step 3:
234 divided by 31 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 217 away from 234, we end up with 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 31

On to step 4:
31 can be fit into 177 5 times, resulting in a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 75.0
Subtract 155 from 177 to get 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 31

Moving on to step 5:
If we divide 225 by 31, we get 7 and a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 757.0
Subtracting 217 from 225 leaves us with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 31

Step 6:
88 divided by 31 is 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 7572.0
Subtract 62 from 88 to get 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 31

Step 7:
31 goes into 260 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 75728.0
Subtract 248 from 260 to get 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 31

On to step 8:
If we divide 122 by 31, we get 3 and a remainder of 29.
The next digit of our result is 3. 
Result so far: 757283.0
If we subtract 93 from 122, we get 29.
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 9:
When dividing 290 by 31, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 757283.9
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.

Moving on to step 10:
When dividing 110 by 31, we get 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 757283.93
Subtract 93 from 110 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 11:
170 divided by 31 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 757283.935
Subtract 155 from 170 to get 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 12:
150 divided by 31 is 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 757283.9354
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.

Step 13:
260 divided by 31 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 757283.93548
Subtract 248 from 260 to 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.

Going ahead to step 14:
31 goes into 120 3 times with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 757283.935483
If we take 93 away from 120, we end up 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.

Moving on to step 15:
If we divide 270 by 31, we get 8 and a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 757283.9354838
The remainder is 22 after subtracting 248 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 16:
The number 31 fits into 220 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 757283.93548387
If we subtract 217 from 220, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 757283.93548387 with a remainder of 3e-09.
