16384590 ÷ 938 
The aim is to understand the frequency of 938 in 16384590.

On to step 1:
The number 938 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 938

Step 2:
16 divided by 938 is 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 938

On to step 3:
The number 938 fits into 163 0 times, leaving a remainder of 163.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 163 after subtracting 0 from 163.
Take the next digit (8) from the dividend and append it to 163, then repeat: 1638 / 938

Moving on to step 4:
When dividing 1638 by 938, we get 1 with a remainder of 700.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 938 away from 1638, we end up with 700.
Grab the next digit (4) from the dividend, add it to 700, then carry on: 7004 / 938

Advancing to step 5:
938 goes into 7004 7 times with a remainder of 438.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 6566 from 7004 to get 438.
Include the next digit (5) from the dividend after 438, then repeat: 4385 / 938

Going ahead to step 6:
938 can be fit into 4385 4 times, resulting in a remainder of 633.
Use 4 as the next digit of our solution. 
Result so far: 174.0
Deduct 3752 from 4385 and we're left with 633.
Bring next digit (9) of the dividend behind the 633 and repeat the process: 6339 / 938

Moving on to step 7:
938 goes into 6339 6 times with a remainder of 711.
Put 6 as the next digit of the answer. 
Result so far: 1746.0
Subtract 5628 from 6339 to get 711.
Grab the next digit (0) from the dividend, add it to 711, then carry on: 7110 / 938

Advancing to step 8:
938 can be fit into 7110 7 times, resulting in a remainder of 544.
Write down 7 as next digit of the result. 
Result so far: 17467.0
If we take 6566 away from 7110, we end up with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

On to step 9:
5440 divided by 938 is 5 with a remainder of 750.
Put 5 as the next digit of the answer. 
Result so far: 17467.5
The remainder is 750 after subtracting 4690 from 5440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Let's proceed to step 10:
7500 divided by 938 is 7 with a remainder of 934.
The next digit of our result is 7. 
Result so far: 17467.57
Subtracting 6566 from 7500 leaves us with 934.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9340, and continue the process.

Going ahead to step 11:
938 goes into 9340 9 times with a remainder of 898.
Put 9 as the next digit of the answer. 
Result so far: 17467.579
Subtracting 8442 from 9340 leaves us with 898.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8980, and continue the process.

Advancing to step 12:
938 can be fit into 8980 9 times, resulting in a remainder of 538.
The next digit of our result is 9. 
Result so far: 17467.5799
Subtracting 8442 from 8980 leaves us with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

The quotient of the division is 17467.5799, and the remainder is 0.00538.
