We're dividing 403954 by 87 
Our goal is to divide 403954 by 87.

Step 1:
4 divided by 87 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 87

Let's proceed to step 2:
The number 87 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 87

Step 3:
When dividing 403 by 87, we get 4 with a remainder of 55.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 348 from 403 and we're left with 55.
Bring next digit (9) of the dividend behind the 55 and repeat the process: 559 / 87

Going ahead to step 4:
87 goes into 559 6 times with a remainder of 37.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
The remainder is 37 after subtracting 522 from 559.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 87

Moving on to step 5:
87 goes into 375 4 times with a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 464.0
If we take 348 away from 375, we end up with 27.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 87

Advancing to step 6:
When dividing 274 by 87, we get 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 4643.0
If we take 261 away from 274, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
The number 87 fits into 130 1 times, leaving a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 4643.1
If we subtract 87 from 130, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 8:
If we divide 430 by 87, we get 4 and a remainder of 82.
Use 4 as the next digit of our solution. 
Result so far: 4643.14
If we take 348 away from 430, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 9:
820 divided by 87 is 9 with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 4643.149
Subtracting 783 from 820 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 10:
370 divided by 87 is 4 with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 4643.1494
Deduct 348 from 370 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
87 goes into 220 2 times with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 4643.14942
Subtracting 174 from 220 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
460 divided by 87 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 4643.149425
Subtracting 435 from 460 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 13:
The number 87 fits into 250 2 times, leaving a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 4643.1494252
Subtracting 174 from 250 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 14:
When dividing 760 by 87, we get 8 with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 4643.14942528
The remainder is 64 after subtracting 696 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 4643.14942528 with a remaining 6.4e-08.
