66508298 divided by 861 
We're looking to find how many times 861 goes into 66508298.

Moving on to step 1:
If we divide 6 by 861, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 861

Going ahead to step 2:
861 can be fit into 66 0 times, resulting in a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Fetch the next digit (5) from the dividend, attach it to 66 and continue: 665 / 861

Let's proceed to step 3:
When dividing 665 by 861, we get 0 with a remainder of 665.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 665 to get 665.
Include the next digit (0) from the dividend after 665, then repeat: 6650 / 861

Let's proceed to step 4:
861 goes into 6650 7 times with a remainder of 623.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 6027 away from 6650, we end up with 623.
Fetch the next digit (8) from the dividend, attach it to 623 and continue: 6238 / 861

Step 5:
When dividing 6238 by 861, we get 7 with a remainder of 211.
The next digit of our result is 7. 
Result so far: 77.0
If we subtract 6027 from 6238, we get 211.
Fetch the next digit (2) from the dividend, attach it to 211 and continue: 2112 / 861

Going ahead to step 6:
When dividing 2112 by 861, we get 2 with a remainder of 390.
Record the quotient 2 as the next digit in the result. 
Result so far: 772.0
Subtracting 1722 from 2112 leaves us with 390.
Grab the next digit (9) from the dividend, add it to 390, then carry on: 3909 / 861

On to step 7:
The number 861 fits into 3909 4 times, leaving a remainder of 465.
The number 4 becomes the next digit in our result. 
Result so far: 7724.0
If we take 3444 away from 3909, we end up with 465.
Take the next digit (8) from the dividend and append it to 465, then repeat: 4658 / 861

Moving on to step 8:
If we divide 4658 by 861, we get 5 and a remainder of 353.
Use 5 as the next digit of our solution. 
Result so far: 77245.0
If we subtract 4305 from 4658, we get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Advancing to step 9:
If we divide 3530 by 861, we get 4 and a remainder of 86.
Use 4 as the next digit of our solution. 
Result so far: 77245.4
The remainder is 86 after subtracting 3444 from 3530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 10:
861 can be fit into 860 0 times, resulting in a remainder of 860.
Write down 0 as next digit of the result. 
Result so far: 77245.4
The remainder is 860 after subtracting 0 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Step 11:
861 can be fit into 8600 9 times, resulting in a remainder of 851.
Write down 9 as next digit of the result. 
Result so far: 77245.409
Subtracting 7749 from 8600 leaves us with 851.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8510, and continue the process.

Let's proceed to step 12:
When dividing 8510 by 861, we get 9 with a remainder of 761.
The next digit of our result is 9. 
Result so far: 77245.4099
The remainder is 761 after subtracting 7749 from 8510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7610, and continue the process.

In conclusion, the division gives 77245.4099 with a balance of 0.00761.
