446399 divided by 87 
We want to divide 446399 by 87.

Advancing to step 1:
87 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 87

Advancing to step 2:
44 divided by 87 is 0 with a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 44, we end up with 44.
Grab the next digit (6) from the dividend, add it to 44, then carry on: 446 / 87

Advancing to step 3:
The number 87 fits into 446 5 times, leaving a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 435 from 446 and we're left with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 87

Let's proceed to step 4:
87 goes into 113 1 times with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 51.0
The remainder is 26 after subtracting 87 from 113.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 87

Going ahead to step 5:
The number 87 fits into 269 3 times, leaving a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 513.0
Subtracting 261 from 269 leaves us with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 87

Moving on to step 6:
The number 87 fits into 89 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 5131.0
The remainder is 2 after subtracting 87 from 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
87 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 5131.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
The number 87 fits into 200 2 times, leaving a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 5131.02
If we take 174 away from 200, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
87 goes into 260 2 times with a remainder of 86.
Use 2 as the next digit of our solution. 
Result so far: 5131.022
Subtracting 174 from 260 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final outcome is 5131.022, with a leftover of 0.0086.
