15816200 ÷ 738 
The aim is to understand the frequency of 738 in 15816200.

Let's proceed to step 1:
738 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 738

On to step 2:
738 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 738

Step 3:
158 divided by 738 is 0 with a remainder of 158.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 158 after subtracting 0 from 158.
Include the next digit (1) from the dividend after 158, then repeat: 1581 / 738

Let's proceed to step 4:
If we divide 1581 by 738, we get 2 and a remainder of 105.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 1476 away from 1581, we end up with 105.
Grab the next digit (6) from the dividend, add it to 105, then carry on: 1056 / 738

Advancing to step 5:
When dividing 1056 by 738, we get 1 with a remainder of 318.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 738 away from 1056, we end up with 318.
Append the next digit (2) from the dividend to 318 and continue with: 3182 / 738

Advancing to step 6:
738 goes into 3182 4 times with a remainder of 230.
The number 4 becomes the next digit in our result. 
Result so far: 214.0
If we subtract 2952 from 3182, we get 230.
Fetch the next digit (0) from the dividend, attach it to 230 and continue: 2300 / 738

Step 7:
738 goes into 2300 3 times with a remainder of 86.
Record the quotient 3 as the next digit in the result. 
Result so far: 2143.0
The remainder is 86 after subtracting 2214 from 2300.
Take the next digit (0) from the dividend and append it to 86, then repeat: 860 / 738

Moving on to step 8:
If we divide 860 by 738, we get 1 and a remainder of 122.
Put 1 as the next digit of the answer. 
Result so far: 21431.0
Subtracting 738 from 860 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 9:
If we divide 1220 by 738, we get 1 and a remainder of 482.
The number 1 becomes the next digit in our result. 
Result so far: 21431.1
If we take 738 away from 1220, we end up with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Step 10:
738 goes into 4820 6 times with a remainder of 392.
Use 6 as the next digit of our solution. 
Result so far: 21431.16
The remainder is 392 after subtracting 4428 from 4820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 11:
The number 738 fits into 3920 5 times, leaving a remainder of 230.
Record the quotient 5 as the next digit in the result. 
Result so far: 21431.165
Subtract 3690 from 3920 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 12:
738 goes into 2300 3 times with a remainder of 86.
The number 3 becomes the next digit in our result. 
Result so far: 21431.1653
Subtracting 2214 from 2300 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 13:
The number 738 fits into 860 1 times, leaving a remainder of 122.
Put 1 as the next digit of the answer. 
Result so far: 21431.16531
If we subtract 738 from 860, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 14:
When dividing 1220 by 738, we get 1 with a remainder of 482.
Use 1 as the next digit of our solution. 
Result so far: 21431.165311
Subtract 738 from 1220 to get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Our division results in 21431.165311 with a remaining 4.82e-05.
