15953776 ÷ 103 
The aim is to understand the frequency of 103 in 15953776.

Step 1:
If we divide 1 by 103, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 103

Moving on to step 2:
The number 103 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 103

Step 3:
103 goes into 159 1 times with a remainder of 56.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 103 from 159, we get 56.
Take the next digit (5) from the dividend and append it to 56, then repeat: 565 / 103

Let's proceed to step 4:
103 can be fit into 565 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 515 away from 565, we end up with 50.
Fetch the next digit (3) from the dividend, attach it to 50 and continue: 503 / 103

Going ahead to step 5:
103 can be fit into 503 4 times, resulting in a remainder of 91.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
Deduct 412 from 503 and we're left with 91.
Bring next digit (7) of the dividend behind the 91 and repeat the process: 917 / 103

Moving on to step 6:
917 divided by 103 is 8 with a remainder of 93.
Use 8 as the next digit of our solution. 
Result so far: 1548.0
The remainder is 93 after subtracting 824 from 917.
Bring next digit (7) of the dividend behind the 93 and repeat the process: 937 / 103

Moving on to step 7:
The number 103 fits into 937 9 times, leaving a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 15489.0
If we take 927 away from 937, we end up with 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 103

Step 8:
When dividing 106 by 103, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 154891.0
If we subtract 103 from 106, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
When dividing 30 by 103, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 154891.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
If we divide 300 by 103, we get 2 and a remainder of 94.
Use 2 as the next digit of our solution. 
Result so far: 154891.02
The remainder is 94 after subtracting 206 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 11:
103 can be fit into 940 9 times, resulting in a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 154891.029
If we subtract 927 from 940, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 12:
103 goes into 130 1 times with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 154891.0291
If we take 103 away from 130, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 13:
The number 103 fits into 270 2 times, leaving a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 154891.02912
The remainder is 64 after subtracting 206 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 14:
If we divide 640 by 103, we get 6 and a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 154891.029126
The remainder is 22 after subtracting 618 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 15:
220 divided by 103 is 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 154891.0291262
Subtract 206 from 220 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 16:
If we divide 140 by 103, we get 1 and a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 154891.02912621
The remainder is 37 after subtracting 103 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

In conclusion, the division gives 154891.02912621 with a balance of 3.7e-08.
