31997459 ÷ 465 
The aim is to understand the frequency of 465 in 31997459.

Going ahead to step 1:
3 divided by 465 is 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.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 465

Going ahead to step 2:
When dividing 31 by 465, we get 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Include the next digit (9) from the dividend after 31, then repeat: 319 / 465

Advancing to step 3:
465 goes into 319 0 times with a remainder of 319.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 319 to get 319.
Grab the next digit (9) from the dividend, add it to 319, then carry on: 3199 / 465

Moving on to step 4:
3199 divided by 465 is 6 with a remainder of 409.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 2790 from 3199 and we're left with 409.
Take the next digit (7) from the dividend and append it to 409, then repeat: 4097 / 465

Moving on to step 5:
4097 divided by 465 is 8 with a remainder of 377.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
The remainder is 377 after subtracting 3720 from 4097.
Grab the next digit (4) from the dividend, add it to 377, then carry on: 3774 / 465

Advancing to step 6:
The number 465 fits into 3774 8 times, leaving a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 688.0
Subtract 3720 from 3774 to get 54.
Bring next digit (5) of the dividend behind the 54 and repeat the process: 545 / 465

On to step 7:
The number 465 fits into 545 1 times, leaving a remainder of 80.
The next digit of our result is 1. 
Result so far: 6881.0
If we subtract 465 from 545, we get 80.
Append the next digit (9) from the dividend to 80 and continue with: 809 / 465

Let's proceed to step 8:
465 can be fit into 809 1 times, resulting in a remainder of 344.
Write down 1 as next digit of the result. 
Result so far: 68811.0
Subtracting 465 from 809 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 9:
465 goes into 3440 7 times with a remainder of 185.
Put 7 as the next digit of the answer. 
Result so far: 68811.7
Subtracting 3255 from 3440 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 10:
If we divide 1850 by 465, we get 3 and a remainder of 455.
The number 3 becomes the next digit in our result. 
Result so far: 68811.73
Subtract 1395 from 1850 to get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Going ahead to step 11:
465 goes into 4550 9 times with a remainder of 365.
The next digit of our result is 9. 
Result so far: 68811.739
Subtract 4185 from 4550 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 12:
465 goes into 3650 7 times with a remainder of 395.
The number 7 becomes the next digit in our result. 
Result so far: 68811.7397
The remainder is 395 after subtracting 3255 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Let's proceed to step 13:
465 can be fit into 3950 8 times, resulting in a remainder of 230.
Record the quotient 8 as the next digit in the result. 
Result so far: 68811.73978
The remainder is 230 after subtracting 3720 from 3950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 14:
When dividing 2300 by 465, we get 4 with a remainder of 440.
Put 4 as the next digit of the answer. 
Result so far: 68811.739784
Deduct 1860 from 2300 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 15:
465 goes into 4400 9 times with a remainder of 215.
Write down 9 as next digit of the result. 
Result so far: 68811.7397849
Subtracting 4185 from 4400 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Advancing to step 16:
When dividing 2150 by 465, we get 4 with a remainder of 290.
Record the quotient 4 as the next digit in the result. 
Result so far: 68811.73978494
Deduct 1860 from 2150 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

The final outcome is 68811.73978494, with a leftover of 2.9e-07.
