We look at the division of 85807151 by 785 
The aim is to understand the frequency of 785 in 85807151.

Step 1:
The number 785 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 785

Advancing to step 2:
85 divided by 785 is 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Take the next digit (8) from the dividend and append it to 85, then repeat: 858 / 785

Let's proceed to step 3:
785 can be fit into 858 1 times, resulting in a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 785 from 858 leaves us with 73.
Take the next digit (0) from the dividend and append it to 73, then repeat: 730 / 785

Advancing to step 4:
If we divide 730 by 785, we get 0 and a remainder of 730.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 730, we get 730.
Include the next digit (7) from the dividend after 730, then repeat: 7307 / 785

Step 5:
The number 785 fits into 7307 9 times, leaving a remainder of 242.
Write down 9 as next digit of the result. 
Result so far: 109.0
Deduct 7065 from 7307 and we're left with 242.
Grab the next digit (1) from the dividend, add it to 242, then carry on: 2421 / 785

Let's proceed to step 6:
785 goes into 2421 3 times with a remainder of 66.
The next digit of our result is 3. 
Result so far: 1093.0
Subtract 2355 from 2421 to get 66.
Fetch the next digit (5) from the dividend, attach it to 66 and continue: 665 / 785

Let's proceed to step 7:
The number 785 fits into 665 0 times, leaving a remainder of 665.
Use 0 as the next digit of our solution. 
Result so far: 10930.0
Subtract 0 from 665 to get 665.
Append the next digit (1) from the dividend to 665 and continue with: 6651 / 785

Let's proceed to step 8:
785 goes into 6651 8 times with a remainder of 371.
Put 8 as the next digit of the answer. 
Result so far: 109308.0
Subtracting 6280 from 6651 leaves us with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Let's proceed to step 9:
If we divide 3710 by 785, we get 4 and a remainder of 570.
The next digit of our result is 4. 
Result so far: 109308.4
If we subtract 3140 from 3710, we get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 10:
5700 divided by 785 is 7 with a remainder of 205.
The next digit of our result is 7. 
Result so far: 109308.47
The remainder is 205 after subtracting 5495 from 5700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 11:
If we divide 2050 by 785, we get 2 and a remainder of 480.
The number 2 becomes the next digit in our result. 
Result so far: 109308.472
Deduct 1570 from 2050 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 12:
When dividing 4800 by 785, we get 6 with a remainder of 90.
Put 6 as the next digit of the answer. 
Result so far: 109308.4726
The remainder is 90 after subtracting 4710 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 13:
If we divide 900 by 785, we get 1 and a remainder of 115.
The next digit of our result is 1. 
Result so far: 109308.47261
Deduct 785 from 900 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 14:
When dividing 1150 by 785, we get 1 with a remainder of 365.
Put 1 as the next digit of the answer. 
Result so far: 109308.472611
If we subtract 785 from 1150, we get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Our division results in 109308.472611 with a remaining 3.65e-05.
