We look at the division of 49887440 by 918 
The aim is to understand the frequency of 918 in 49887440.

On to step 1:
If we divide 4 by 918, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 918

Step 2:
If we divide 49 by 918, we get 0 and a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Take the next digit (8) from the dividend and append it to 49, then repeat: 498 / 918

Moving on to step 3:
498 divided by 918 is 0 with a remainder of 498.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 498 leaves us with 498.
Take the next digit (8) from the dividend and append it to 498, then repeat: 4988 / 918

Going ahead to step 4:
When dividing 4988 by 918, we get 5 with a remainder of 398.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 398 after subtracting 4590 from 4988.
Append the next digit (7) from the dividend to 398 and continue with: 3987 / 918

Moving on to step 5:
3987 divided by 918 is 4 with a remainder of 315.
Use 4 as the next digit of our solution. 
Result so far: 54.0
Deduct 3672 from 3987 and we're left with 315.
Take the next digit (4) from the dividend and append it to 315, then repeat: 3154 / 918

Moving on to step 6:
918 can be fit into 3154 3 times, resulting in a remainder of 400.
Record the quotient 3 as the next digit in the result. 
Result so far: 543.0
Subtracting 2754 from 3154 leaves us with 400.
Take the next digit (4) from the dividend and append it to 400, then repeat: 4004 / 918

Going ahead to step 7:
4004 divided by 918 is 4 with a remainder of 332.
Use 4 as the next digit of our solution. 
Result so far: 5434.0
If we take 3672 away from 4004, we end up with 332.
Include the next digit (0) from the dividend after 332, then repeat: 3320 / 918

Let's proceed to step 8:
918 can be fit into 3320 3 times, resulting in a remainder of 566.
The number 3 becomes the next digit in our result. 
Result so far: 54343.0
Deduct 2754 from 3320 and we're left with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Let's proceed to step 9:
The number 918 fits into 5660 6 times, leaving a remainder of 152.
Write down 6 as next digit of the result. 
Result so far: 54343.6
The remainder is 152 after subtracting 5508 from 5660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 10:
The number 918 fits into 1520 1 times, leaving a remainder of 602.
Write down 1 as next digit of the result. 
Result so far: 54343.61
Subtract 918 from 1520 to get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Going ahead to step 11:
918 can be fit into 6020 6 times, resulting in a remainder of 512.
Put 6 as the next digit of the answer. 
Result so far: 54343.616
If we take 5508 away from 6020, we end up with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

On to step 12:
5120 divided by 918 is 5 with a remainder of 530.
Put 5 as the next digit of the answer. 
Result so far: 54343.6165
Subtract 4590 from 5120 to get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

On to step 13:
5300 divided by 918 is 5 with a remainder of 710.
Put 5 as the next digit of the answer. 
Result so far: 54343.61655
The remainder is 710 after subtracting 4590 from 5300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

The quotient of the division is 54343.61655, and the remainder is 0.00071.
