Let's divide 385478 by 86
We're looking to find how many times 86 goes into 385478.

Step 1:
If we divide 3 by 86, we get 0 and 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 (8) from the dividend, attach it to 3 and continue: 38 / 86

Going ahead to step 2:
The number 86 fits into 38 0 times, leaving a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Fetch the next digit (5) from the dividend, attach it to 38 and continue: 385 / 86

Going ahead to step 3:
The number 86 fits into 385 4 times, leaving a remainder of 41.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 41 after subtracting 344 from 385.
Fetch the next digit (4) from the dividend, attach it to 41 and continue: 414 / 86

Step 4:
If we divide 414 by 86, we get 4 and a remainder of 70.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
The remainder is 70 after subtracting 344 from 414.
Include the next digit (7) from the dividend after 70, then repeat: 707 / 86

Advancing to step 5:
86 can be fit into 707 8 times, resulting in a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 448.0
If we take 688 away from 707, we end up with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 86

Advancing to step 6:
When dividing 198 by 86, we get 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 4482.0
Deduct 172 from 198 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
260 divided by 86 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 4482.3
Deduct 258 from 260 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
The number 86 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 4482.3
Deduct 0 from 20 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.

On to step 9:
The number 86 fits into 200 2 times, leaving a remainder of 28.
The next digit of our result is 2. 
Result so far: 4482.302
If we take 172 away from 200, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
The number 86 fits into 280 3 times, leaving a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 4482.3023
If we subtract 258 from 280, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
The number 86 fits into 220 2 times, leaving a remainder of 48.
The next digit of our result is 2. 
Result so far: 4482.30232
The remainder is 48 after subtracting 172 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
If we divide 480 by 86, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 4482.302325
Subtracting 430 from 480 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
500 divided by 86 is 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 4482.3023255
Deduct 430 from 500 and we're left 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.

The final result is 4482.3023255 with a remainder of 7e-07.
