We divide 86550591 by 394
We want to figure out the number of times 86550591 can be divided by 394.

Advancing to step 1:
When dividing 8 by 394, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 394

Moving on to step 2:
394 can be fit into 86 0 times, resulting in a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Grab the next digit (5) from the dividend, add it to 86, then carry on: 865 / 394

Moving on to step 3:
394 can be fit into 865 2 times, resulting in a remainder of 77.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 77 after subtracting 788 from 865.
Take the next digit (5) from the dividend and append it to 77, then repeat: 775 / 394

On to step 4:
394 goes into 775 1 times with a remainder of 381.
The next digit of our result is 1. 
Result so far: 21.0
Subtract 394 from 775 to get 381.
Append the next digit (0) from the dividend to 381 and continue with: 3810 / 394

Let's proceed to step 5:
394 goes into 3810 9 times with a remainder of 264.
The number 9 becomes the next digit in our result. 
Result so far: 219.0
If we take 3546 away from 3810, we end up with 264.
Append the next digit (5) from the dividend to 264 and continue with: 2645 / 394

Advancing to step 6:
394 can be fit into 2645 6 times, resulting in a remainder of 281.
The number 6 becomes the next digit in our result. 
Result so far: 2196.0
If we take 2364 away from 2645, we end up with 281.
Take the next digit (9) from the dividend and append it to 281, then repeat: 2819 / 394

Let's proceed to step 7:
394 can be fit into 2819 7 times, resulting in a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 21967.0
The remainder is 61 after subtracting 2758 from 2819.
Bring next digit (1) of the dividend behind the 61 and repeat the process: 611 / 394

Going ahead to step 8:
394 goes into 611 1 times with a remainder of 217.
Put 1 as the next digit of the answer. 
Result so far: 219671.0
The remainder is 217 after subtracting 394 from 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Moving on to step 9:
394 goes into 2170 5 times with a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 219671.5
Subtracting 1970 from 2170 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 10:
2000 divided by 394 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 219671.55
Subtracting 1970 from 2000 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 219671.55, and the remainder is 0.03.
