We look at the division of 9155385 by 531 
Let's see how many times 531 fits into 9155385.

Going ahead to step 1:
The number 531 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 531

Step 2:
When dividing 91 by 531, we get 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Include the next digit (5) from the dividend after 91, then repeat: 915 / 531

Going ahead to step 3:
531 can be fit into 915 1 times, resulting in a remainder of 384.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 531 from 915 to get 384.
Grab the next digit (5) from the dividend, add it to 384, then carry on: 3845 / 531

Advancing to step 4:
531 can be fit into 3845 7 times, resulting in a remainder of 128.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 128 after subtracting 3717 from 3845.
Append the next digit (3) from the dividend to 128 and continue with: 1283 / 531

Advancing to step 5:
1283 divided by 531 is 2 with a remainder of 221.
Use 2 as the next digit of our solution. 
Result so far: 172.0
If we take 1062 away from 1283, we end up with 221.
Include the next digit (8) from the dividend after 221, then repeat: 2218 / 531

Moving on to step 6:
531 goes into 2218 4 times with a remainder of 94.
Use 4 as the next digit of our solution. 
Result so far: 1724.0
If we take 2124 away from 2218, we end up with 94.
Fetch the next digit (5) from the dividend, attach it to 94 and continue: 945 / 531

Step 7:
If we divide 945 by 531, we get 1 and a remainder of 414.
The next digit of our result is 1. 
Result so far: 17241.0
Deduct 531 from 945 and we're left with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 8:
When dividing 4140 by 531, we get 7 with a remainder of 423.
The next digit of our result is 7. 
Result so far: 17241.7
Subtracting 3717 from 4140 leaves us with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Moving on to step 9:
531 can be fit into 4230 7 times, resulting in a remainder of 513.
The next digit of our result is 7. 
Result so far: 17241.77
Subtracting 3717 from 4230 leaves us with 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

The final result is 17241.77 with a remainder of 0.513.
