We look at the division of 50521951 by 465 
The aim is to understand the frequency of 465 in 50521951.

On to step 1:
When dividing 5 by 465, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 465

Let's proceed to step 2:
If we divide 50 by 465, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Append the next digit (5) from the dividend to 50 and continue with: 505 / 465

Moving on to step 3:
If we divide 505 by 465, we get 1 and a remainder of 40.
The next digit of our result is 1. 
Result so far: 1.0
If we take 465 away from 505, we end up with 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 465

Advancing to step 4:
402 divided by 465 is 0 with a remainder of 402.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 402, we end up with 402.
Append the next digit (1) from the dividend to 402 and continue with: 4021 / 465

Advancing to step 5:
The number 465 fits into 4021 8 times, leaving a remainder of 301.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
Subtracting 3720 from 4021 leaves us with 301.
Grab the next digit (9) from the dividend, add it to 301, then carry on: 3019 / 465

Let's proceed to step 6:
When dividing 3019 by 465, we get 6 with a remainder of 229.
The next digit of our result is 6. 
Result so far: 1086.0
Subtract 2790 from 3019 to get 229.
Include the next digit (5) from the dividend after 229, then repeat: 2295 / 465

Advancing to step 7:
465 can be fit into 2295 4 times, resulting in a remainder of 435.
The number 4 becomes the next digit in our result. 
Result so far: 10864.0
Subtracting 1860 from 2295 leaves us with 435.
Bring next digit (1) of the dividend behind the 435 and repeat the process: 4351 / 465

Let's proceed to step 8:
4351 divided by 465 is 9 with a remainder of 166.
Put 9 as the next digit of the answer. 
Result so far: 108649.0
Subtract 4185 from 4351 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 9:
If we divide 1660 by 465, we get 3 and a remainder of 265.
The number 3 becomes the next digit in our result. 
Result so far: 108649.3
Subtract 1395 from 1660 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 10:
2650 divided by 465 is 5 with a remainder of 325.
Put 5 as the next digit of the answer. 
Result so far: 108649.35
Deduct 2325 from 2650 and we're left with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 11:
If we divide 3250 by 465, we get 6 and a remainder of 460.
Write down 6 as next digit of the result. 
Result so far: 108649.356
Subtract 2790 from 3250 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 12:
4600 divided by 465 is 9 with a remainder of 415.
The next digit of our result is 9. 
Result so far: 108649.3569
The remainder is 415 after subtracting 4185 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Advancing to step 13:
When dividing 4150 by 465, we get 8 with a remainder of 430.
Write down 8 as next digit of the result. 
Result so far: 108649.35698
Subtracting 3720 from 4150 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 14:
If we divide 4300 by 465, we get 9 and a remainder of 115.
Put 9 as the next digit of the answer. 
Result so far: 108649.356989
Deduct 4185 from 4300 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 15:
When dividing 1150 by 465, we get 2 with a remainder of 220.
Put 2 as the next digit of the answer. 
Result so far: 108649.3569892
If we subtract 930 from 1150, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 16:
The number 465 fits into 2200 4 times, leaving a remainder of 340.
Use 4 as the next digit of our solution. 
Result so far: 108649.35698924
If we take 1860 away from 2200, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

After the division, we end up with 108649.35698924 and a remainder of 3.4e-07.
