352431 ÷ 87 
We want to divide 352431 by 87.

Let's proceed to step 1:
When dividing 3 by 87, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 87

Advancing to step 2:
If we divide 35 by 87, we get 0 and a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Bring next digit (2) of the dividend behind the 35 and repeat the process: 352 / 87

On to step 3:
The number 87 fits into 352 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 348 from 352 leaves us with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 87

Let's proceed to step 4:
The number 87 fits into 44 0 times, leaving a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtracting 0 from 44 leaves us with 44.
Bring next digit (3) of the dividend behind the 44 and repeat the process: 443 / 87

Let's proceed to step 5:
87 goes into 443 5 times with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 405.0
The remainder is 8 after subtracting 435 from 443.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 87

Step 6:
87 can be fit into 81 0 times, resulting in a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 4050.0
Subtracting 0 from 81 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 7:
The number 87 fits into 810 9 times, leaving a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 4050.9
If we take 783 away from 810, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 8:
87 goes into 270 3 times with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 4050.93
If we take 261 away from 270, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
When dividing 90 by 87, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 4050.931
If we subtract 87 from 90, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
The number 87 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 4050.931
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
300 divided by 87 is 3 with a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 4050.93103
If we subtract 261 from 300, 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.

On to step 12:
The number 87 fits into 390 4 times, leaving a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 4050.931034
If we take 348 away from 390, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
87 can be fit into 420 4 times, resulting in a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 4050.9310344
If we subtract 348 from 420, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 4050.9310344, and the remainder is 7.2e-07.
