31078904 ÷ 258 
The aim is to understand the frequency of 258 in 31078904.

Moving on to step 1:
When dividing 3 by 258, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 258

Moving on to step 2:
258 goes into 31 0 times with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 258

Advancing to step 3:
258 goes into 310 1 times with a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 258 from 310 and we're left with 52.
Fetch the next digit (7) from the dividend, attach it to 52 and continue: 527 / 258

Moving on to step 4:
527 divided by 258 is 2 with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 11 after subtracting 516 from 527.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 258

Going ahead to step 5:
The number 258 fits into 118 0 times, leaving a remainder of 118.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
Subtract 0 from 118 to get 118.
Include the next digit (9) from the dividend after 118, then repeat: 1189 / 258

Let's proceed to step 6:
If we divide 1189 by 258, we get 4 and a remainder of 157.
Write down 4 as next digit of the result. 
Result so far: 1204.0
Subtracting 1032 from 1189 leaves us with 157.
Include the next digit (0) from the dividend after 157, then repeat: 1570 / 258

Advancing to step 7:
When dividing 1570 by 258, we get 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 12046.0
The remainder is 22 after subtracting 1548 from 1570.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 258

Step 8:
258 goes into 224 0 times with a remainder of 224.
Record the quotient 0 as the next digit in the result. 
Result so far: 120460.0
If we take 0 away from 224, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 9:
If we divide 2240 by 258, we get 8 and a remainder of 176.
Put 8 as the next digit of the answer. 
Result so far: 120460.8
Deduct 2064 from 2240 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 10:
258 goes into 1760 6 times with a remainder of 212.
Use 6 as the next digit of our solution. 
Result so far: 120460.86
Deduct 1548 from 1760 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 11:
2120 divided by 258 is 8 with a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 120460.868
The remainder is 56 after subtracting 2064 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 12:
258 goes into 560 2 times with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 120460.8682
Subtract 516 from 560 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
If we divide 440 by 258, we get 1 and a remainder of 182.
Put 1 as the next digit of the answer. 
Result so far: 120460.86821
If we take 258 away from 440, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Going ahead to step 14:
258 goes into 1820 7 times with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 120460.868217
The remainder is 14 after subtracting 1806 from 1820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 15:
258 can be fit into 140 0 times, resulting in a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 120460.868217
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 16:
When dividing 1400 by 258, we get 5 with a remainder of 110.
Write down 5 as next digit of the result. 
Result so far: 120460.86821705
If we subtract 1290 from 1400, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final outcome is 120460.86821705, with a leftover of 1.1e-07.
