899551 ÷ 87 
We want to figure out the number of times 899551 can be divided by 87.

Going ahead to step 1:
87 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 87

Going ahead to step 2:
87 goes into 89 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 87 from 89, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 87

Let's proceed to step 3:
The number 87 fits into 29 0 times, leaving a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 29 leaves us with 29.
Take the next digit (5) from the dividend and append it to 29, then repeat: 295 / 87

On to step 4:
87 goes into 295 3 times with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 103.0
If we take 261 away from 295, we end up with 34.
Grab the next digit (5) from the dividend, add it to 34, then carry on: 345 / 87

Step 5:
When dividing 345 by 87, we get 3 with a remainder of 84.
Put 3 as the next digit of the answer. 
Result so far: 1033.0
Subtract 261 from 345 to get 84.
Take the next digit (1) from the dividend and append it to 84, then repeat: 841 / 87

Advancing to step 6:
The number 87 fits into 841 9 times, leaving a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 10339.0
If we subtract 783 from 841, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 7:
When dividing 580 by 87, we get 6 with a remainder of 58.
Write down 6 as next digit of the result. 
Result so far: 10339.6
If we take 522 away from 580, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 8:
580 divided by 87 is 6 with a remainder of 58.
The next digit of our result is 6. 
Result so far: 10339.66
The remainder is 58 after subtracting 522 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final outcome is 10339.66, with a leftover of 0.058.
