86379364 ÷ 223 
We want to figure out the number of times 86379364 can be divided by 223.

On to step 1:
223 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 223

Moving on to step 2:
If we divide 86 by 223, we get 0 and a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Fetch the next digit (3) from the dividend, attach it to 86 and continue: 863 / 223

Step 3:
When dividing 863 by 223, we get 3 with a remainder of 194.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 669 from 863, we get 194.
Fetch the next digit (7) from the dividend, attach it to 194 and continue: 1947 / 223

On to step 4:
The number 223 fits into 1947 8 times, leaving a remainder of 163.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Deduct 1784 from 1947 and we're left with 163.
Bring next digit (9) of the dividend behind the 163 and repeat the process: 1639 / 223

On to step 5:
When dividing 1639 by 223, we get 7 with a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 387.0
If we take 1561 away from 1639, we end up with 78.
Take the next digit (3) from the dividend and append it to 78, then repeat: 783 / 223

Moving on to step 6:
783 divided by 223 is 3 with a remainder of 114.
Record the quotient 3 as the next digit in the result. 
Result so far: 3873.0
If we subtract 669 from 783, we get 114.
Take the next digit (6) from the dividend and append it to 114, then repeat: 1146 / 223

Going ahead to step 7:
223 can be fit into 1146 5 times, resulting in a remainder of 31.
Put 5 as the next digit of the answer. 
Result so far: 38735.0
Subtracting 1115 from 1146 leaves us with 31.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 223

Moving on to step 8:
314 divided by 223 is 1 with a remainder of 91.
The next digit of our result is 1. 
Result so far: 387351.0
Deduct 223 from 314 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 9:
The number 223 fits into 910 4 times, leaving a remainder of 18.
The next digit of our result is 4. 
Result so far: 387351.4
Subtracting 892 from 910 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
If we divide 180 by 223, we get 0 and a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 387351.4
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 11:
The number 223 fits into 1800 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 387351.408
Subtract 1784 from 1800 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
If we divide 160 by 223, we get 0 and a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 387351.408
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
When dividing 1600 by 223, we get 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 387351.40807
If we subtract 1561 from 1600, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 14:
223 goes into 390 1 times with a remainder of 167.
The number 1 becomes the next digit in our result. 
Result so far: 387351.408071
If we take 223 away from 390, we end up with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Advancing to step 15:
223 goes into 1670 7 times with a remainder of 109.
The next digit of our result is 7. 
Result so far: 387351.4080717
If we subtract 1561 from 1670, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 16:
1090 divided by 223 is 4 with a remainder of 198.
Write down 4 as next digit of the result. 
Result so far: 387351.40807174
The remainder is 198 after subtracting 892 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

In conclusion, the division gives 387351.40807174 with a balance of 1.98e-07.
