We're dividing 438064 by 87 
Let's see how many times 87 fits into 438064.

Going ahead to step 1:
87 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 87

Going ahead to step 2:
When dividing 43 by 87, we get 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 87

Advancing to step 3:
When dividing 438 by 87, we get 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 435 from 438 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 87

Advancing to step 4:
When dividing 30 by 87, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 87

Advancing to step 5:
87 can be fit into 306 3 times, resulting in a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 503.0
Subtract 261 from 306 to get 45.
Append the next digit (4) from the dividend to 45 and continue with: 454 / 87

Going ahead to step 6:
454 divided by 87 is 5 with a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 5035.0
If we take 435 away from 454, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
87 can be fit into 190 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 5035.2
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.

On to step 8:
87 goes into 160 1 times with a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 5035.21
If we subtract 87 from 160, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 9:
The number 87 fits into 730 8 times, leaving a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 5035.218
If we subtract 696 from 730, we get 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 10:
87 can be fit into 340 3 times, resulting in a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 5035.2183
If we subtract 261 from 340, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 11:
790 divided by 87 is 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 5035.21839
Deduct 783 from 790 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 12:
If we divide 70 by 87, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 5035.21839
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 13:
87 goes into 700 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 5035.2183908
The remainder is 4 after subtracting 696 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
When dividing 40 by 87, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 5035.2183908
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 5035.2183908, with a leftover of 4e-08.
