66149157 ÷ 103 
The aim is to understand the frequency of 103 in 66149157.

Advancing to step 1:
The number 103 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 103

Going ahead to step 2:
66 divided by 103 is 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 103

Let's proceed to step 3:
The number 103 fits into 661 6 times, leaving a remainder of 43.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 43 after subtracting 618 from 661.
Fetch the next digit (4) from the dividend, attach it to 43 and continue: 434 / 103

Going ahead to step 4:
The number 103 fits into 434 4 times, leaving a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 64.0
The remainder is 22 after subtracting 412 from 434.
Fetch the next digit (9) from the dividend, attach it to 22 and continue: 229 / 103

Let's proceed to step 5:
When dividing 229 by 103, we get 2 with a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 642.0
If we take 206 away from 229, we end up with 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 103

Step 6:
The number 103 fits into 231 2 times, leaving a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 6422.0
Deduct 206 from 231 and we're left with 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 103

Let's proceed to step 7:
If we divide 255 by 103, we get 2 and a remainder of 49.
Put 2 as the next digit of the answer. 
Result so far: 64222.0
If we subtract 206 from 255, we get 49.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 103

Moving on to step 8:
If we divide 497 by 103, we get 4 and a remainder of 85.
Use 4 as the next digit of our solution. 
Result so far: 642224.0
Subtract 412 from 497 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 9:
If we divide 850 by 103, we get 8 and a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 642224.8
If we take 824 away from 850, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
260 divided by 103 is 2 with a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 642224.82
Subtracting 206 from 260 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 11:
If we divide 540 by 103, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 642224.825
Subtracting 515 from 540 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 12:
When dividing 250 by 103, we get 2 with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 642224.8252
The remainder is 44 after subtracting 206 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
When dividing 440 by 103, we get 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 642224.82524
Deduct 412 from 440 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 14:
When dividing 280 by 103, we get 2 with a remainder of 74.
Write down 2 as next digit of the result. 
Result so far: 642224.825242
Deduct 206 from 280 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 15:
103 goes into 740 7 times with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 642224.8252427
Deduct 721 from 740 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 16:
190 divided by 103 is 1 with a remainder of 87.
The next digit of our result is 1. 
Result so far: 642224.82524271
Subtract 103 from 190 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

After the division, we end up with 642224.82524271 and a remainder of 8.7e-08.
