86655771 divided by 393 
We want to figure out the number of times 86655771 can be divided by 393.

Let's proceed to step 1:
393 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 393

Moving on to step 2:
If we divide 86 by 393, we get 0 and a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Grab the next digit (6) from the dividend, add it to 86, then carry on: 866 / 393

Step 3:
393 goes into 866 2 times with a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 786 away from 866, we end up with 80.
Append the next digit (5) from the dividend to 80 and continue with: 805 / 393

Let's proceed to step 4:
805 divided by 393 is 2 with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 786 from 805 to get 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 393

On to step 5:
195 divided by 393 is 0 with a remainder of 195.
Use 0 as the next digit of our solution. 
Result so far: 220.0
The remainder is 195 after subtracting 0 from 195.
Append the next digit (7) from the dividend to 195 and continue with: 1957 / 393

Advancing to step 6:
When dividing 1957 by 393, we get 4 with a remainder of 385.
Use 4 as the next digit of our solution. 
Result so far: 2204.0
Subtracting 1572 from 1957 leaves us with 385.
Bring next digit (7) of the dividend behind the 385 and repeat the process: 3857 / 393

Going ahead to step 7:
393 can be fit into 3857 9 times, resulting in a remainder of 320.
Use 9 as the next digit of our solution. 
Result so far: 22049.0
If we subtract 3537 from 3857, we get 320.
Include the next digit (1) from the dividend after 320, then repeat: 3201 / 393

Step 8:
393 can be fit into 3201 8 times, resulting in a remainder of 57.
Put 8 as the next digit of the answer. 
Result so far: 220498.0
Subtracting 3144 from 3201 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 9:
393 can be fit into 570 1 times, resulting in a remainder of 177.
Write down 1 as next digit of the result. 
Result so far: 220498.1
Subtracting 393 from 570 leaves us with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Step 10:
When dividing 1770 by 393, we get 4 with a remainder of 198.
Write down 4 as next digit of the result. 
Result so far: 220498.14
If we take 1572 away from 1770, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 11:
The number 393 fits into 1980 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 220498.145
The remainder is 15 after subtracting 1965 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
The number 393 fits into 150 0 times, leaving a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 220498.145
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 13:
393 can be fit into 1500 3 times, resulting in a remainder of 321.
Put 3 as the next digit of the answer. 
Result so far: 220498.14503
If we subtract 1179 from 1500, we get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Step 14:
When dividing 3210 by 393, we get 8 with a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 220498.145038
If we subtract 3144 from 3210, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 15:
If we divide 660 by 393, we get 1 and a remainder of 267.
The next digit of our result is 1. 
Result so far: 220498.1450381
The remainder is 267 after subtracting 393 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Step 16:
The number 393 fits into 2670 6 times, leaving a remainder of 312.
The number 6 becomes the next digit in our result. 
Result so far: 220498.14503816
Deduct 2358 from 2670 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The quotient of the division is 220498.14503816, and the remainder is 3.12e-07.
