We divide 66511734 by 858
We want to figure out the number of times 66511734 can be divided by 858.

Let's proceed to step 1:
858 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 858

On to step 2:
The number 858 fits into 66 0 times, leaving a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 858

Moving on to step 3:
665 divided by 858 is 0 with a remainder of 665.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 665, we get 665.
Take the next digit (1) from the dividend and append it to 665, then repeat: 6651 / 858

Step 4:
When dividing 6651 by 858, we get 7 with a remainder of 645.
The next digit of our result is 7. 
Result so far: 7.0
If we take 6006 away from 6651, we end up with 645.
Bring next digit (1) of the dividend behind the 645 and repeat the process: 6451 / 858

Advancing to step 5:
6451 divided by 858 is 7 with a remainder of 445.
The next digit of our result is 7. 
Result so far: 77.0
The remainder is 445 after subtracting 6006 from 6451.
Take the next digit (7) from the dividend and append it to 445, then repeat: 4457 / 858

Let's proceed to step 6:
The number 858 fits into 4457 5 times, leaving a remainder of 167.
Use 5 as the next digit of our solution. 
Result so far: 775.0
If we take 4290 away from 4457, we end up with 167.
Fetch the next digit (3) from the dividend, attach it to 167 and continue: 1673 / 858

Moving on to step 7:
If we divide 1673 by 858, we get 1 and a remainder of 815.
The number 1 becomes the next digit in our result. 
Result so far: 7751.0
Subtract 858 from 1673 to get 815.
Fetch the next digit (4) from the dividend, attach it to 815 and continue: 8154 / 858

Moving on to step 8:
If we divide 8154 by 858, we get 9 and a remainder of 432.
Record the quotient 9 as the next digit in the result. 
Result so far: 77519.0
If we subtract 7722 from 8154, we get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 9:
If we divide 4320 by 858, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 77519.5
Deduct 4290 from 4320 and we're left 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.

On to step 10:
858 goes into 300 0 times with a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 77519.5
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 11:
The number 858 fits into 3000 3 times, leaving a remainder of 426.
The next digit of our result is 3. 
Result so far: 77519.503
If we subtract 2574 from 3000, we get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Let's proceed to step 12:
4260 divided by 858 is 4 with a remainder of 828.
Record the quotient 4 as the next digit in the result. 
Result so far: 77519.5034
Deduct 3432 from 4260 and we're left with 828.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8280, and continue the process.

Going ahead to step 13:
The number 858 fits into 8280 9 times, leaving a remainder of 558.
Write down 9 as next digit of the result. 
Result so far: 77519.50349
If we take 7722 away from 8280, we end up with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Going ahead to step 14:
5580 divided by 858 is 6 with a remainder of 432.
Record the quotient 6 as the next digit in the result. 
Result so far: 77519.503496
Subtracting 5148 from 5580 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Going ahead to step 15:
858 can be fit into 4320 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 77519.5034965
Deduct 4290 from 4320 and we're left 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.

Let's proceed to step 16:
300 divided by 858 is 0 with a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 77519.5034965
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final result is 77519.5034965 with a remainder of 3e-07.
