74802949 divided by 31 
The aim is to understand the frequency of 31 in 74802949.

On to step 1:
If we divide 7 by 31, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 31

Let's proceed to step 2:
If we divide 74 by 31, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 2.0
If we take 62 away from 74, we end up with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 31

Going ahead to step 3:
When dividing 128 by 31, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we take 124 away from 128, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 31

Moving on to step 4:
40 divided by 31 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 241.0
Subtract 31 from 40 to get 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 31

Let's proceed to step 5:
The number 31 fits into 92 2 times, leaving a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 2412.0
Subtract 62 from 92 to get 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 31

Moving on to step 6:
31 goes into 309 9 times with a remainder of 30.
The next digit of our result is 9. 
Result so far: 24129.0
Subtract 279 from 309 to get 30.
Bring next digit (4) of the dividend behind the 30 and repeat the process: 304 / 31

On to step 7:
304 divided by 31 is 9 with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 241299.0
Deduct 279 from 304 and we're left with 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 31

Going ahead to step 8:
When dividing 259 by 31, we get 8 with a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 2412998.0
Subtract 248 from 259 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.

Going ahead to step 9:
When dividing 110 by 31, we get 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 2412998.3
The remainder is 17 after subtracting 93 from 110.
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 10:
31 can be fit into 170 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 2412998.35
The remainder is 15 after subtracting 155 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
When dividing 150 by 31, we get 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 2412998.354
If we take 124 away from 150, we end up 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.

Advancing to step 12:
If we divide 260 by 31, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 2412998.3548
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.

Advancing to step 13:
31 can be fit into 120 3 times, resulting in a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 2412998.35483
If we subtract 93 from 120, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 14:
31 can be fit into 270 8 times, resulting in a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 2412998.354838
Subtract 248 from 270 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 15:
The number 31 fits into 220 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 2412998.3548387
The remainder is 3 after subtracting 217 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 16:
If we divide 30 by 31, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 2412998.3548387
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 2412998.3548387, with a leftover of 3e-08.
