Let's divide 381380 by 87
We want to figure out the number of times 381380 can be divided by 87.

Advancing to step 1:
87 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 87

Step 2:
38 divided by 87 is 0 with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 87

Let's proceed to step 3:
When dividing 381 by 87, we get 4 with a remainder of 33.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 348 from 381 and we're left with 33.
Include the next digit (3) from the dividend after 33, then repeat: 333 / 87

Let's proceed to step 4:
When dividing 333 by 87, we get 3 with a remainder of 72.
Use 3 as the next digit of our solution. 
Result so far: 43.0
The remainder is 72 after subtracting 261 from 333.
Include the next digit (8) from the dividend after 72, then repeat: 728 / 87

Let's proceed to step 5:
87 goes into 728 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 438.0
If we subtract 696 from 728, we get 32.
Fetch the next digit (0) from the dividend, attach it to 32 and continue: 320 / 87

Moving on to step 6:
The number 87 fits into 320 3 times, leaving a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 4383.0
Deduct 261 from 320 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 7:
The number 87 fits into 590 6 times, leaving a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 4383.6
Subtracting 522 from 590 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 8:
87 can be fit into 680 7 times, resulting in a remainder of 71.
The next digit of our result is 7. 
Result so far: 4383.67
The remainder is 71 after subtracting 609 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 9:
If we divide 710 by 87, we get 8 and a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 4383.678
The remainder is 14 after subtracting 696 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
87 can be fit into 140 1 times, resulting in a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 4383.6781
Subtracting 87 from 140 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 11:
If we divide 530 by 87, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 4383.67816
Deduct 522 from 530 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
The number 87 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 4383.67816
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
If we divide 800 by 87, we get 9 and a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 4383.6781609
If we take 783 away from 800, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 14:
When dividing 170 by 87, we get 1 with a remainder of 83.
Put 1 as the next digit of the answer. 
Result so far: 4383.67816091
The remainder is 83 after subtracting 87 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

The final result is 4383.67816091 with a remainder of 8.3e-08.
