Let's divide 51311512 by 418
The aim is to understand the frequency of 418 in 51311512.

Going ahead to step 1:
418 can be fit into 5 0 times, resulting in 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.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 418

Advancing to step 2:
418 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 418

Moving on to step 3:
The number 418 fits into 513 1 times, leaving a remainder of 95.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 418 from 513 and we're left with 95.
Take the next digit (1) from the dividend and append it to 95, then repeat: 951 / 418

Let's proceed to step 4:
The number 418 fits into 951 2 times, leaving a remainder of 115.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 836 from 951 to get 115.
Take the next digit (1) from the dividend and append it to 115, then repeat: 1151 / 418

Moving on to step 5:
1151 divided by 418 is 2 with a remainder of 315.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
Deduct 836 from 1151 and we're left with 315.
Append the next digit (5) from the dividend to 315 and continue with: 3155 / 418

Moving on to step 6:
418 can be fit into 3155 7 times, resulting in a remainder of 229.
The next digit of our result is 7. 
Result so far: 1227.0
Deduct 2926 from 3155 and we're left with 229.
Grab the next digit (1) from the dividend, add it to 229, then carry on: 2291 / 418

Step 7:
If we divide 2291 by 418, we get 5 and a remainder of 201.
The number 5 becomes the next digit in our result. 
Result so far: 12275.0
Subtract 2090 from 2291 to get 201.
Fetch the next digit (2) from the dividend, attach it to 201 and continue: 2012 / 418

Step 8:
If we divide 2012 by 418, we get 4 and a remainder of 340.
The next digit of our result is 4. 
Result so far: 122754.0
If we subtract 1672 from 2012, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 9:
If we divide 3400 by 418, we get 8 and a remainder of 56.
The next digit of our result is 8. 
Result so far: 122754.8
If we take 3344 away from 3400, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 10:
418 can be fit into 560 1 times, resulting in a remainder of 142.
Write down 1 as next digit of the result. 
Result so far: 122754.81
Deduct 418 from 560 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 11:
418 can be fit into 1420 3 times, resulting in a remainder of 166.
The next digit of our result is 3. 
Result so far: 122754.813
Subtracting 1254 from 1420 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 12:
When dividing 1660 by 418, we get 3 with a remainder of 406.
The number 3 becomes the next digit in our result. 
Result so far: 122754.8133
If we take 1254 away from 1660, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

In conclusion, the division gives 122754.8133 with a balance of 0.00406.
