We look at the division of 337899 by 87 
We want to divide 337899 by 87.

Advancing to step 1:
The number 87 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 87

Advancing to step 2:
87 can be fit into 33 0 times, resulting in a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Fetch the next digit (7) from the dividend, attach it to 33 and continue: 337 / 87

Advancing to step 3:
87 goes into 337 3 times with a remainder of 76.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 261 from 337 leaves us with 76.
Bring next digit (8) of the dividend behind the 76 and repeat the process: 768 / 87

Let's proceed to step 4:
768 divided by 87 is 8 with a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we subtract 696 from 768, we get 72.
Fetch the next digit (9) from the dividend, attach it to 72 and continue: 729 / 87

Let's proceed to step 5:
87 can be fit into 729 8 times, resulting in a remainder of 33.
The next digit of our result is 8. 
Result so far: 388.0
Deduct 696 from 729 and we're left with 33.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 87

Let's proceed to step 6:
When dividing 339 by 87, we get 3 with a remainder of 78.
The number 3 becomes the next digit in our result. 
Result so far: 3883.0
If we take 261 away from 339, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 7:
If we divide 780 by 87, we get 8 and a remainder of 84.
Record the quotient 8 as the next digit in the result. 
Result so far: 3883.8
Subtract 696 from 780 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 8:
When dividing 840 by 87, we get 9 with a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 3883.89
Subtracting 783 from 840 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 9:
87 goes into 570 6 times with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 3883.896
If we subtract 522 from 570, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
If we divide 480 by 87, we get 5 and a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 3883.8965
If we take 435 away from 480, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 11:
87 goes into 450 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 3883.89655
Subtracting 435 from 450 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 3883.89655, and the remainder is 1.5e-05.
