72337870 divided by 518 
The aim is to understand the frequency of 518 in 72337870.

On to step 1:
If we divide 7 by 518, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 518

Step 2:
The number 518 fits into 72 0 times, leaving a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Fetch the next digit (3) from the dividend, attach it to 72 and continue: 723 / 518

On to step 3:
If we divide 723 by 518, we get 1 and a remainder of 205.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 518 away from 723, we end up with 205.
Append the next digit (3) from the dividend to 205 and continue with: 2053 / 518

Step 4:
518 goes into 2053 3 times with a remainder of 499.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 499 after subtracting 1554 from 2053.
Take the next digit (7) from the dividend and append it to 499, then repeat: 4997 / 518

Advancing to step 5:
If we divide 4997 by 518, we get 9 and a remainder of 335.
Write down 9 as next digit of the result. 
Result so far: 139.0
If we take 4662 away from 4997, we end up with 335.
Bring next digit (8) of the dividend behind the 335 and repeat the process: 3358 / 518

Moving on to step 6:
If we divide 3358 by 518, we get 6 and a remainder of 250.
Put 6 as the next digit of the answer. 
Result so far: 1396.0
Subtracting 3108 from 3358 leaves us with 250.
Take the next digit (7) from the dividend and append it to 250, then repeat: 2507 / 518

Step 7:
2507 divided by 518 is 4 with a remainder of 435.
Write down 4 as next digit of the result. 
Result so far: 13964.0
If we take 2072 away from 2507, we end up with 435.
Grab the next digit (0) from the dividend, add it to 435, then carry on: 4350 / 518

Let's proceed to step 8:
518 goes into 4350 8 times with a remainder of 206.
Use 8 as the next digit of our solution. 
Result so far: 139648.0
Subtract 4144 from 4350 to get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Going ahead to step 9:
2060 divided by 518 is 3 with a remainder of 506.
Write down 3 as next digit of the result. 
Result so far: 139648.3
If we subtract 1554 from 2060, we get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Let's proceed to step 10:
5060 divided by 518 is 9 with a remainder of 398.
Write down 9 as next digit of the result. 
Result so far: 139648.39
If we take 4662 away from 5060, we end up with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Let's proceed to step 11:
3980 divided by 518 is 7 with a remainder of 354.
Put 7 as the next digit of the answer. 
Result so far: 139648.397
The remainder is 354 after subtracting 3626 from 3980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Let's proceed to step 12:
518 can be fit into 3540 6 times, resulting in a remainder of 432.
Use 6 as the next digit of our solution. 
Result so far: 139648.3976
Deduct 3108 from 3540 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 13:
When dividing 4320 by 518, we get 8 with a remainder of 176.
The next digit of our result is 8. 
Result so far: 139648.39768
The remainder is 176 after subtracting 4144 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 14:
518 can be fit into 1760 3 times, resulting in a remainder of 206.
The next digit of our result is 3. 
Result so far: 139648.397683
Subtracting 1554 from 1760 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 15:
518 can be fit into 2060 3 times, resulting in a remainder of 506.
The number 3 becomes the next digit in our result. 
Result so far: 139648.3976833
The remainder is 506 after subtracting 1554 from 2060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

The quotient of the division is 139648.3976833, and the remainder is 5.06e-06.
