We're dividing 403719 by 87 
We're looking to find how many times 87 goes into 403719.

Moving on to step 1:
4 divided by 87 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 87

Advancing to step 2:
When dividing 40 by 87, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 87

Moving on to step 3:
87 goes into 403 4 times with a remainder of 55.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 55 after subtracting 348 from 403.
Include the next digit (7) from the dividend after 55, then repeat: 557 / 87

Moving on to step 4:
87 goes into 557 6 times with a remainder of 35.
Write down 6 as next digit of the result. 
Result so far: 46.0
Subtract 522 from 557 to get 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 87

Step 5:
When dividing 351 by 87, we get 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 464.0
Deduct 348 from 351 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 87

On to step 6:
87 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 4640.0
If we subtract 0 from 39, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 7:
The number 87 fits into 390 4 times, leaving a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 4640.4
If we subtract 348 from 390, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
87 can be fit into 420 4 times, resulting in a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 4640.44
The remainder is 72 after subtracting 348 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 4640.44 with a remaining 0.072.
