We look at the division of 378089 by 87 
Our goal is to divide 378089 by 87.

On to step 1:
When dividing 3 by 87, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 87

On to step 2:
87 goes into 37 0 times with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 87

Advancing to step 3:
The number 87 fits into 378 4 times, leaving a remainder of 30.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 348 from 378, we get 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 87

Moving on to step 4:
If we divide 300 by 87, we get 3 and a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtracting 261 from 300 leaves us with 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 87

Going ahead to step 5:
If we divide 398 by 87, we get 4 and a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 434.0
Deduct 348 from 398 and we're left with 50.
Grab the next digit (9) from the dividend, add it to 50, then carry on: 509 / 87

Advancing to step 6:
87 goes into 509 5 times with a remainder of 74.
The next digit of our result is 5. 
Result so far: 4345.0
Subtracting 435 from 509 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 7:
If we divide 740 by 87, we get 8 and a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 4345.8
If we take 696 away from 740, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 8:
87 can be fit into 440 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 4345.85
Subtract 435 from 440 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
When dividing 50 by 87, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 4345.85
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
87 goes into 500 5 times with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 4345.8505
Subtract 435 from 500 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 11:
When dividing 650 by 87, we get 7 with a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 4345.85057
Subtracting 609 from 650 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 12:
410 divided by 87 is 4 with a remainder of 62.
The next digit of our result is 4. 
Result so far: 4345.850574
Subtracting 348 from 410 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 13:
The number 87 fits into 620 7 times, leaving a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 4345.8505747
Subtracting 609 from 620 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 14:
110 divided by 87 is 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 4345.85057471
If we subtract 87 from 110, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

In conclusion, the division gives 4345.85057471 with a balance of 2.3e-08.
