We're dividing 85715520 by 383 
The aim is to understand the frequency of 383 in 85715520.

On to step 1:
If we divide 8 by 383, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 383

Going ahead to step 2:
If we divide 85 by 383, we get 0 and a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Fetch the next digit (7) from the dividend, attach it to 85 and continue: 857 / 383

Going ahead to step 3:
When dividing 857 by 383, we get 2 with a remainder of 91.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 766 from 857 leaves us with 91.
Fetch the next digit (1) from the dividend, attach it to 91 and continue: 911 / 383

Step 4:
When dividing 911 by 383, we get 2 with a remainder of 145.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 766 from 911, we get 145.
Append the next digit (5) from the dividend to 145 and continue with: 1455 / 383

Advancing to step 5:
1455 divided by 383 is 3 with a remainder of 306.
Put 3 as the next digit of the answer. 
Result so far: 223.0
If we subtract 1149 from 1455, we get 306.
Take the next digit (5) from the dividend and append it to 306, then repeat: 3065 / 383

Going ahead to step 6:
383 goes into 3065 8 times with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 2238.0
Deduct 3064 from 3065 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 383

Moving on to step 7:
383 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 22380.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 383

On to step 8:
When dividing 120 by 383, we get 0 with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 223800.0
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 9:
When dividing 1200 by 383, we get 3 with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 223800.3
Subtracting 1149 from 1200 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 10:
When dividing 510 by 383, we get 1 with a remainder of 127.
The next digit of our result is 1. 
Result so far: 223800.31
Subtract 383 from 510 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Let's proceed to step 11:
When dividing 1270 by 383, we get 3 with a remainder of 121.
Write down 3 as next digit of the result. 
Result so far: 223800.313
Subtract 1149 from 1270 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Let's proceed to step 12:
If we divide 1210 by 383, we get 3 and a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 223800.3133
Subtract 1149 from 1210 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

After the division, we end up with 223800.3133 and a remainder of 0.00061.
