Let's divide 385531 by 87
We're looking to find how many times 87 goes into 385531.

Step 1:
When dividing 3 by 87, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 87

Step 2:
The number 87 fits into 38 0 times, leaving a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Fetch the next digit (5) from the dividend, attach it to 38 and continue: 385 / 87

On to step 3:
If we divide 385 by 87, we get 4 and a remainder of 37.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 348 from 385 and we're left with 37.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 87

On to step 4:
If we divide 375 by 87, we get 4 and a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 44.0
The remainder is 27 after subtracting 348 from 375.
Grab the next digit (3) from the dividend, add it to 27, then carry on: 273 / 87

On to step 5:
If we divide 273 by 87, we get 3 and a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 443.0
If we subtract 261 from 273, we get 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 87

On to step 6:
121 divided by 87 is 1 with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 4431.0
Subtract 87 from 121 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
340 divided by 87 is 3 with a remainder of 79.
Record the quotient 3 as the next digit in the result. 
Result so far: 4431.3
If we take 261 away from 340, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 8:
The number 87 fits into 790 9 times, leaving a remainder of 7.
The next digit of our result is 9. 
Result so far: 4431.39
Deduct 783 from 790 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
87 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 4431.39
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
87 goes into 700 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 4431.3908
Subtracting 696 from 700 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
The number 87 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 4431.3908
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
87 can be fit into 400 4 times, resulting in a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 4431.390804
Subtract 348 from 400 to 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.

Let's proceed to step 13:
520 divided by 87 is 5 with a remainder of 85.
The next digit of our result is 5. 
Result so far: 4431.3908045
Subtract 435 from 520 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 14:
87 can be fit into 850 9 times, resulting in a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 4431.39080459
If we subtract 783 from 850, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The final outcome is 4431.39080459, with a leftover of 6.7e-08.
