Let's divide 70512925 by 103
The aim is to understand the frequency of 103 in 70512925.

Going ahead to step 1:
When dividing 7 by 103, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 103

Advancing to step 2:
103 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Grab the next digit (5) from the dividend, add it to 70, then carry on: 705 / 103

Going ahead to step 3:
103 can be fit into 705 6 times, resulting in a remainder of 87.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 618 from 705 to get 87.
Bring next digit (1) of the dividend behind the 87 and repeat the process: 871 / 103

Advancing to step 4:
103 goes into 871 8 times with a remainder of 47.
Put 8 as the next digit of the answer. 
Result so far: 68.0
Deduct 824 from 871 and we're left with 47.
Grab the next digit (2) from the dividend, add it to 47, then carry on: 472 / 103

Moving on to step 5:
103 can be fit into 472 4 times, resulting in a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 684.0
Subtracting 412 from 472 leaves us with 60.
Bring next digit (9) of the dividend behind the 60 and repeat the process: 609 / 103

Let's proceed to step 6:
When dividing 609 by 103, we get 5 with a remainder of 94.
Use 5 as the next digit of our solution. 
Result so far: 6845.0
If we take 515 away from 609, we end up with 94.
Take the next digit (2) from the dividend and append it to 94, then repeat: 942 / 103

Advancing to step 7:
942 divided by 103 is 9 with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 68459.0
Deduct 927 from 942 and we're left with 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 103

Step 8:
The number 103 fits into 155 1 times, leaving a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 684591.0
If we subtract 103 from 155, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
The number 103 fits into 520 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 684591.5
Subtracting 515 from 520 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
If we divide 50 by 103, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 684591.5
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
When dividing 500 by 103, we get 4 with a remainder of 88.
Record the quotient 4 as the next digit in the result. 
Result so far: 684591.504
Subtracting 412 from 500 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 12:
When dividing 880 by 103, we get 8 with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 684591.5048
Subtract 824 from 880 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 13:
When dividing 560 by 103, we get 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 684591.50485
Subtracting 515 from 560 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 14:
When dividing 450 by 103, we get 4 with a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 684591.504854
Subtract 412 from 450 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 15:
103 goes into 380 3 times with a remainder of 71.
The next digit of our result is 3. 
Result so far: 684591.5048543
If we take 309 away from 380, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 16:
103 goes into 710 6 times with a remainder of 92.
Record the quotient 6 as the next digit in the result. 
Result so far: 684591.50485436
If we subtract 618 from 710, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

After the division, we end up with 684591.50485436 and a remainder of 9.2e-08.
