We look at the division of 378303 by 89 
We want to figure out the number of times 378303 can be divided by 89.

On to step 1:
89 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 89

Moving on to step 2:
When dividing 37 by 89, we get 0 with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 89

On to step 3:
When dividing 378 by 89, we get 4 with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 356 away from 378, we end up with 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 89

Going ahead to step 4:
89 goes into 223 2 times with a remainder of 45.
The next digit of our result is 2. 
Result so far: 42.0
Subtracting 178 from 223 leaves us with 45.
Bring next digit (0) of the dividend behind the 45 and repeat the process: 450 / 89

Advancing to step 5:
When dividing 450 by 89, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 425.0
If we subtract 445 from 450, we get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 89

Advancing to step 6:
When dividing 53 by 89, we get 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 4250.0
The remainder is 53 after subtracting 0 from 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 7:
530 divided by 89 is 5 with a remainder of 85.
The next digit of our result is 5. 
Result so far: 4250.5
Subtract 445 from 530 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 8:
89 can be fit into 850 9 times, resulting in a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 4250.59
The remainder is 49 after subtracting 801 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 9:
490 divided by 89 is 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 4250.595
If we subtract 445 from 490, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 10:
The number 89 fits into 450 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 4250.5955
The remainder is 5 after subtracting 445 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 4250.5955 with a balance of 5e-05.
