4991340 divided by 16 
The aim is to understand the frequency of 16 in 4991340.

On to step 1:
16 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 16

Advancing to step 2:
16 goes into 49 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 48 from 49 to get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 16

Moving on to step 3:
When dividing 19 by 16, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 16 from 19 and we're left with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 16

Moving on to step 4:
16 can be fit into 31 1 times, resulting in a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 311.0
Subtract 16 from 31 to get 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 16

Advancing to step 5:
16 goes into 153 9 times with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 3119.0
If we subtract 144 from 153, we get 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 16

Advancing to step 6:
94 divided by 16 is 5 with a remainder of 14.
The next digit of our result is 5. 
Result so far: 31195.0
Subtracting 80 from 94 leaves us with 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 16

Advancing to step 7:
The number 16 fits into 140 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 311958.0
Subtract 128 from 140 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
16 can be fit into 120 7 times, resulting in a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 311958.7
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 311958.75
Deduct 80 from 80 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 311958.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
0 divided by 16 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 311958.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 311958.75, and the remainder is 0.0.
