445555 ÷ 31 
The aim is to understand the frequency of 31 in 445555.

Advancing to step 1:
If we divide 4 by 31, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 31

Advancing to step 2:
44 divided by 31 is 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 13 after subtracting 31 from 44.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 31

Moving on to step 3:
If we divide 135 by 31, we get 4 and a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 124 from 135 leaves us with 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 31

Going ahead to step 4:
When dividing 115 by 31, we get 3 with a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 143.0
If we take 93 away from 115, we end up with 22.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 31

Let's proceed to step 5:
When dividing 225 by 31, we get 7 with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 1437.0
Subtracting 217 from 225 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 31

Step 6:
The number 31 fits into 85 2 times, leaving a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 14372.0
The remainder is 23 after subtracting 62 from 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
The number 31 fits into 230 7 times, leaving a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 14372.7
Subtract 217 from 230 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 8:
130 divided by 31 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 14372.74
If we take 124 away from 130, 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.

Let's proceed to step 9:
31 can be fit into 60 1 times, resulting in a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 14372.741
Deduct 31 from 60 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 10:
31 can be fit into 290 9 times, resulting in a remainder of 11.
The next digit of our result is 9. 
Result so far: 14372.7419
The remainder is 11 after subtracting 279 from 290.
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 11:
If we divide 110 by 31, we get 3 and a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 14372.74193
If we take 93 away from 110, we end up 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.

Advancing to step 12:
170 divided by 31 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 14372.741935
If we take 155 away from 170, we end up 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.

Step 13:
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: 14372.7419354
The remainder is 26 after subtracting 124 from 150.
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 14:
When dividing 260 by 31, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 14372.74193548
Deduct 248 from 260 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 14372.74193548, with a leftover of 1.2e-08.
