51412665 ÷ 617 
The aim is to understand the frequency of 617 in 51412665.

On to step 1:
5 divided by 617 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 617

Going ahead to step 2:
617 can be fit into 51 0 times, resulting in a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Append the next digit (4) from the dividend to 51 and continue with: 514 / 617

Let's proceed to step 3:
617 can be fit into 514 0 times, resulting in a remainder of 514.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 514, we get 514.
Bring next digit (1) of the dividend behind the 514 and repeat the process: 5141 / 617

Moving on to step 4:
When dividing 5141 by 617, we get 8 with a remainder of 205.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 205 after subtracting 4936 from 5141.
Bring next digit (2) of the dividend behind the 205 and repeat the process: 2052 / 617

Let's proceed to step 5:
The number 617 fits into 2052 3 times, leaving a remainder of 201.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Subtract 1851 from 2052 to get 201.
Bring next digit (6) of the dividend behind the 201 and repeat the process: 2016 / 617

Going ahead to step 6:
2016 divided by 617 is 3 with a remainder of 165.
Put 3 as the next digit of the answer. 
Result so far: 833.0
If we take 1851 away from 2016, we end up with 165.
Grab the next digit (6) from the dividend, add it to 165, then carry on: 1656 / 617

Advancing to step 7:
617 can be fit into 1656 2 times, resulting in a remainder of 422.
Put 2 as the next digit of the answer. 
Result so far: 8332.0
If we subtract 1234 from 1656, we get 422.
Take the next digit (5) from the dividend and append it to 422, then repeat: 4225 / 617

On to step 8:
617 can be fit into 4225 6 times, resulting in a remainder of 523.
The number 6 becomes the next digit in our result. 
Result so far: 83326.0
Subtracting 3702 from 4225 leaves us with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

On to step 9:
The number 617 fits into 5230 8 times, leaving a remainder of 294.
Write down 8 as next digit of the result. 
Result so far: 83326.8
The remainder is 294 after subtracting 4936 from 5230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Step 10:
The number 617 fits into 2940 4 times, leaving a remainder of 472.
Use 4 as the next digit of our solution. 
Result so far: 83326.84
Deduct 2468 from 2940 and we're left with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Going ahead to step 11:
If we divide 4720 by 617, we get 7 and a remainder of 401.
Write down 7 as next digit of the result. 
Result so far: 83326.847
Subtracting 4319 from 4720 leaves us with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Going ahead to step 12:
When dividing 4010 by 617, we get 6 with a remainder of 308.
Record the quotient 6 as the next digit in the result. 
Result so far: 83326.8476
If we take 3702 away from 4010, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 13:
The number 617 fits into 3080 4 times, leaving a remainder of 612.
Record the quotient 4 as the next digit in the result. 
Result so far: 83326.84764
If we subtract 2468 from 3080, we get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Moving on to step 14:
617 can be fit into 6120 9 times, resulting in a remainder of 567.
The number 9 becomes the next digit in our result. 
Result so far: 83326.847649
If we subtract 5553 from 6120, we get 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Going ahead to step 15:
617 goes into 5670 9 times with a remainder of 117.
Write down 9 as next digit of the result. 
Result so far: 83326.8476499
The remainder is 117 after subtracting 5553 from 5670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

The final outcome is 83326.8476499, with a leftover of 1.17e-06.
