81037589 divided by 103 
The aim is to understand the frequency of 103 in 81037589.

Going ahead to step 1:
103 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 103

Advancing to step 2:
103 can be fit into 81 0 times, resulting in a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (0) from the dividend, attach it to 81 and continue: 810 / 103

Step 3:
The number 103 fits into 810 7 times, leaving a remainder of 89.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 721 away from 810, we end up with 89.
Append the next digit (3) from the dividend to 89 and continue with: 893 / 103

Let's proceed to step 4:
When dividing 893 by 103, we get 8 with a remainder of 69.
Use 8 as the next digit of our solution. 
Result so far: 78.0
Deduct 824 from 893 and we're left with 69.
Bring next digit (7) of the dividend behind the 69 and repeat the process: 697 / 103

Advancing to step 5:
If we divide 697 by 103, we get 6 and a remainder of 79.
The next digit of our result is 6. 
Result so far: 786.0
Subtract 618 from 697 to get 79.
Include the next digit (5) from the dividend after 79, then repeat: 795 / 103

Going ahead to step 6:
103 goes into 795 7 times with a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 7867.0
If we subtract 721 from 795, we get 74.
Fetch the next digit (8) from the dividend, attach it to 74 and continue: 748 / 103

Advancing to step 7:
The number 103 fits into 748 7 times, leaving a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 78677.0
The remainder is 27 after subtracting 721 from 748.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 103

Let's proceed to step 8:
103 goes into 279 2 times with a remainder of 73.
Record the quotient 2 as the next digit in the result. 
Result so far: 786772.0
If we take 206 away from 279, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 9:
When dividing 730 by 103, we get 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 786772.7
If we subtract 721 from 730, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
If we divide 90 by 103, we get 0 and a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 786772.7
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 11:
If we divide 900 by 103, we get 8 and a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 786772.708
If we subtract 824 from 900, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 12:
103 goes into 760 7 times with a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 786772.7087
The remainder is 39 after subtracting 721 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 13:
The number 103 fits into 390 3 times, leaving a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 786772.70873
Subtract 309 from 390 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 14:
If we divide 810 by 103, we get 7 and a remainder of 89.
Write down 7 as next digit of the result. 
Result so far: 786772.708737
Subtracting 721 from 810 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 15:
103 goes into 890 8 times with a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 786772.7087378
The remainder is 66 after subtracting 824 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 16:
660 divided by 103 is 6 with a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 786772.70873786
Subtract 618 from 660 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 786772.70873786, with a leftover of 4.2e-08.
