51432618 divided by 718 
The aim is to understand the frequency of 718 in 51432618.

Going ahead to step 1:
If we divide 5 by 718, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 718

On to step 2:
51 divided by 718 is 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (4) from the dividend, attach it to 51 and continue: 514 / 718

Moving on to step 3:
514 divided by 718 is 0 with a remainder of 514.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 514 after subtracting 0 from 514.
Append the next digit (3) from the dividend to 514 and continue with: 5143 / 718

Moving on to step 4:
718 can be fit into 5143 7 times, resulting in a remainder of 117.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 117 after subtracting 5026 from 5143.
Take the next digit (2) from the dividend and append it to 117, then repeat: 1172 / 718

Step 5:
1172 divided by 718 is 1 with a remainder of 454.
Write down 1 as next digit of the result. 
Result so far: 71.0
Subtracting 718 from 1172 leaves us with 454.
Append the next digit (6) from the dividend to 454 and continue with: 4546 / 718

On to step 6:
718 can be fit into 4546 6 times, resulting in a remainder of 238.
Use 6 as the next digit of our solution. 
Result so far: 716.0
Subtracting 4308 from 4546 leaves us with 238.
Append the next digit (1) from the dividend to 238 and continue with: 2381 / 718

Advancing to step 7:
The number 718 fits into 2381 3 times, leaving a remainder of 227.
Write down 3 as next digit of the result. 
Result so far: 7163.0
Subtract 2154 from 2381 to get 227.
Grab the next digit (8) from the dividend, add it to 227, then carry on: 2278 / 718

Let's proceed to step 8:
718 goes into 2278 3 times with a remainder of 124.
Write down 3 as next digit of the result. 
Result so far: 71633.0
Subtract 2154 from 2278 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 9:
If we divide 1240 by 718, we get 1 and a remainder of 522.
The number 1 becomes the next digit in our result. 
Result so far: 71633.1
If we take 718 away from 1240, we end up with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Let's proceed to step 10:
When dividing 5220 by 718, we get 7 with a remainder of 194.
Write down 7 as next digit of the result. 
Result so far: 71633.17
Subtracting 5026 from 5220 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Moving on to step 11:
718 goes into 1940 2 times with a remainder of 504.
The number 2 becomes the next digit in our result. 
Result so far: 71633.172
If we take 1436 away from 1940, we end up with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Going ahead to step 12:
When dividing 5040 by 718, we get 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 71633.1727
If we subtract 5026 from 5040, we get 14.
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 13:
718 goes into 140 0 times with a remainder of 140.
The next digit of our result is 0. 
Result so far: 71633.1727
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 14:
When dividing 1400 by 718, we get 1 with a remainder of 682.
Put 1 as the next digit of the answer. 
Result so far: 71633.172701
If we subtract 718 from 1400, we get 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Moving on to step 15:
718 goes into 6820 9 times with a remainder of 358.
Record the quotient 9 as the next digit in the result. 
Result so far: 71633.1727019
If we subtract 6462 from 6820, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Advancing to step 16:
3580 divided by 718 is 4 with a remainder of 708.
Put 4 as the next digit of the answer. 
Result so far: 71633.17270194
If we subtract 2872 from 3580, we get 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

The final result is 71633.17270194 with a remainder of 7.08e-07.
