858218 ÷ 73 
We're looking to find how many times 73 goes into 858218.

Step 1:
When dividing 8 by 73, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 73

Step 2:
73 goes into 85 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 73 from 85 and we're left with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 73

Moving on to step 3:
73 goes into 128 1 times with a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 73 from 128, we get 55.
Grab the next digit (2) from the dividend, add it to 55, then carry on: 552 / 73

Going ahead to step 4:
The number 73 fits into 552 7 times, leaving a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 117.0
Deduct 511 from 552 and we're left with 41.
Include the next digit (1) from the dividend after 41, then repeat: 411 / 73

Going ahead to step 5:
73 goes into 411 5 times with a remainder of 46.
The next digit of our result is 5. 
Result so far: 1175.0
The remainder is 46 after subtracting 365 from 411.
Include the next digit (8) from the dividend after 46, then repeat: 468 / 73

Let's proceed to step 6:
If we divide 468 by 73, we get 6 and a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 11756.0
Subtract 438 from 468 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.

On to step 7:
73 goes into 300 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 11756.4
Subtract 292 from 300 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
If we divide 80 by 73, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 11756.41
Deduct 73 from 80 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
70 divided by 73 is 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 11756.41
Deduct 0 from 70 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.

Going ahead to step 10:
73 goes into 700 9 times with a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 11756.4109
Subtracting 657 from 700 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 11:
When dividing 430 by 73, we get 5 with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 11756.41095
Deduct 365 from 430 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 12:
When dividing 650 by 73, we get 8 with a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 11756.410958
The remainder is 66 after subtracting 584 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 13:
73 goes into 660 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 11756.4109589
If we take 657 away from 660, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 14:
30 divided by 73 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 11756.4109589
If we take 0 away from 30, we end up 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.

In conclusion, the division gives 11756.4109589 with a balance of 3e-08.
