290851 divided by 87 
Our goal is to divide 290851 by 87.

On to step 1:
If we divide 2 by 87, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 87

Going ahead to step 2:
The number 87 fits into 29 0 times, leaving a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 87

Let's proceed to step 3:
290 divided by 87 is 3 with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 261 from 290 and we're left with 29.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 87

Going ahead to step 4:
The number 87 fits into 298 3 times, leaving a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
The remainder is 37 after subtracting 261 from 298.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 87

On to step 5:
When dividing 375 by 87, we get 4 with a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 334.0
If we take 348 away from 375, we end up with 27.
Grab the next digit (1) from the dividend, add it to 27, then carry on: 271 / 87

On to step 6:
87 goes into 271 3 times with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 3343.0
Subtract 261 from 271 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
The number 87 fits into 100 1 times, leaving a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 3343.1
The remainder is 13 after subtracting 87 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 8:
When dividing 130 by 87, we get 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 3343.11
If we subtract 87 from 130, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The final result is 3343.11 with a remainder of 0.043.
