We're dividing 350641 by 87 
We want to divide 350641 by 87.

Step 1:
87 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 87

Going ahead to step 2:
If we divide 35 by 87, we get 0 and a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 87

Let's proceed to step 3:
350 divided by 87 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 348 away from 350, we end up with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 87

Let's proceed to step 4:
26 divided by 87 is 0 with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Deduct 0 from 26 and we're left with 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 87

Advancing to step 5:
The number 87 fits into 264 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 403.0
Subtract 261 from 264 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 87

Advancing to step 6:
87 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 4030.0
Subtracting 0 from 31 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
87 can be fit into 310 3 times, resulting in a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 4030.3
Subtract 261 from 310 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 8:
The number 87 fits into 490 5 times, leaving a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 4030.35
If we take 435 away from 490, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 9:
The number 87 fits into 550 6 times, leaving a remainder of 28.
The next digit of our result is 6. 
Result so far: 4030.356
Subtract 522 from 550 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
When dividing 280 by 87, we get 3 with a remainder of 19.
The next digit of our result is 3. 
Result so far: 4030.3563
Subtract 261 from 280 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 11:
If we divide 190 by 87, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 4030.35632
The remainder is 16 after subtracting 174 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
The number 87 fits into 160 1 times, leaving a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 4030.356321
The remainder is 73 after subtracting 87 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 13:
730 divided by 87 is 8 with a remainder of 34.
The next digit of our result is 8. 
Result so far: 4030.3563218
Subtracting 696 from 730 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 14:
87 can be fit into 340 3 times, resulting in a remainder of 79.
The next digit of our result is 3. 
Result so far: 4030.35632183
The remainder is 79 after subtracting 261 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

The final result is 4030.35632183 with a remainder of 7.9e-08.
