We divide 74851065 by 903
The aim is to understand the frequency of 903 in 74851065.

On to step 1:
If we divide 7 by 903, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 903

Going ahead to step 2:
When dividing 74 by 903, we get 0 with a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Fetch the next digit (8) from the dividend, attach it to 74 and continue: 748 / 903

Moving on to step 3:
When dividing 748 by 903, we get 0 with a remainder of 748.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 748, we end up with 748.
Bring next digit (5) of the dividend behind the 748 and repeat the process: 7485 / 903

Advancing to step 4:
903 goes into 7485 8 times with a remainder of 261.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 7224 from 7485 leaves us with 261.
Append the next digit (1) from the dividend to 261 and continue with: 2611 / 903

Moving on to step 5:
2611 divided by 903 is 2 with a remainder of 805.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
Subtracting 1806 from 2611 leaves us with 805.
Grab the next digit (0) from the dividend, add it to 805, then carry on: 8050 / 903

Let's proceed to step 6:
903 goes into 8050 8 times with a remainder of 826.
Use 8 as the next digit of our solution. 
Result so far: 828.0
The remainder is 826 after subtracting 7224 from 8050.
Grab the next digit (6) from the dividend, add it to 826, then carry on: 8266 / 903

Going ahead to step 7:
If we divide 8266 by 903, we get 9 and a remainder of 139.
Write down 9 as next digit of the result. 
Result so far: 8289.0
If we take 8127 away from 8266, we end up with 139.
Include the next digit (5) from the dividend after 139, then repeat: 1395 / 903

Let's proceed to step 8:
903 goes into 1395 1 times with a remainder of 492.
The number 1 becomes the next digit in our result. 
Result so far: 82891.0
If we subtract 903 from 1395, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

On to step 9:
903 can be fit into 4920 5 times, resulting in a remainder of 405.
Use 5 as the next digit of our solution. 
Result so far: 82891.5
Deduct 4515 from 4920 and we're left with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 10:
If we divide 4050 by 903, we get 4 and a remainder of 438.
The next digit of our result is 4. 
Result so far: 82891.54
If we subtract 3612 from 4050, we get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Step 11:
If we divide 4380 by 903, we get 4 and a remainder of 768.
The next digit of our result is 4. 
Result so far: 82891.544
Deduct 3612 from 4380 and we're left with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

The final outcome is 82891.544, with a leftover of 0.0768.
