We're dividing 378376 by 85 
Our goal is to divide 378376 by 85.

Going ahead to step 1:
When dividing 3 by 85, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
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 / 85

Moving on to step 2:
37 divided by 85 is 0 with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 85

Step 3:
85 goes into 378 4 times with a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 340 away from 378, we end up with 38.
Include the next digit (3) from the dividend after 38, then repeat: 383 / 85

Going ahead to step 4:
The number 85 fits into 383 4 times, leaving a remainder of 43.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
If we take 340 away from 383, we end up with 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 85

On to step 5:
437 divided by 85 is 5 with a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 445.0
Deduct 425 from 437 and we're left with 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 85

Advancing to step 6:
85 can be fit into 126 1 times, resulting in a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 4451.0
If we take 85 away from 126, we end up 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.

Let's proceed to step 7:
If we divide 410 by 85, we get 4 and a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 4451.4
Subtract 340 from 410 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
85 can be fit into 700 8 times, resulting in a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 4451.48
Deduct 680 from 700 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
When dividing 200 by 85, we get 2 with a remainder of 30.
The next digit of our result is 2. 
Result so far: 4451.482
Subtract 170 from 200 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
The number 85 fits into 300 3 times, leaving a remainder of 45.
The next digit of our result is 3. 
Result so far: 4451.4823
Deduct 255 from 300 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 11:
If we divide 450 by 85, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 4451.48235
Subtracting 425 from 450 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 12:
250 divided by 85 is 2 with a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 4451.482352
Deduct 170 from 250 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.

Advancing to step 13:
The number 85 fits into 800 9 times, leaving a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 4451.4823529
Deduct 765 from 800 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 14:
85 can be fit into 350 4 times, resulting in a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 4451.48235294
Deduct 340 from 350 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 4451.48235294, with a leftover of 1e-08.
