Let's divide 14290455 by 861
We're looking to find how many times 861 goes into 14290455.

On to step 1:
When dividing 1 by 861, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 861

Let's proceed to step 2:
861 goes into 14 0 times with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 861

Going ahead to step 3:
142 divided by 861 is 0 with a remainder of 142.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 142 after subtracting 0 from 142.
Append the next digit (9) from the dividend to 142 and continue with: 1429 / 861

On to step 4:
861 goes into 1429 1 times with a remainder of 568.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 861 from 1429, we get 568.
Append the next digit (0) from the dividend to 568 and continue with: 5680 / 861

On to step 5:
When dividing 5680 by 861, we get 6 with a remainder of 514.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 5166 from 5680 leaves us with 514.
Append the next digit (4) from the dividend to 514 and continue with: 5144 / 861

Moving on to step 6:
861 goes into 5144 5 times with a remainder of 839.
Put 5 as the next digit of the answer. 
Result so far: 165.0
The remainder is 839 after subtracting 4305 from 5144.
Bring next digit (5) of the dividend behind the 839 and repeat the process: 8395 / 861

Let's proceed to step 7:
861 goes into 8395 9 times with a remainder of 646.
The next digit of our result is 9. 
Result so far: 1659.0
If we subtract 7749 from 8395, we get 646.
Bring next digit (5) of the dividend behind the 646 and repeat the process: 6465 / 861

Advancing to step 8:
When dividing 6465 by 861, we get 7 with a remainder of 438.
Write down 7 as next digit of the result. 
Result so far: 16597.0
If we subtract 6027 from 6465, we get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

On to step 9:
861 goes into 4380 5 times with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 16597.5
Subtract 4305 from 4380 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 10:
750 divided by 861 is 0 with a remainder of 750.
Write down 0 as next digit of the result. 
Result so far: 16597.5
If we subtract 0 from 750, we get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 11:
861 can be fit into 7500 8 times, resulting in a remainder of 612.
Put 8 as the next digit of the answer. 
Result so far: 16597.508
The remainder is 612 after subtracting 6888 from 7500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Moving on to step 12:
The number 861 fits into 6120 7 times, leaving a remainder of 93.
Record the quotient 7 as the next digit in the result. 
Result so far: 16597.5087
If we take 6027 away from 6120, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 13:
930 divided by 861 is 1 with a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 16597.50871
Deduct 861 from 930 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 14:
When dividing 690 by 861, we get 0 with a remainder of 690.
The number 0 becomes the next digit in our result. 
Result so far: 16597.50871
If we subtract 0 from 690, we get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Step 15:
The number 861 fits into 6900 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 16597.5087108
If we subtract 6888 from 6900, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 16:
If we divide 120 by 861, we get 0 and a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 16597.5087108
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

In conclusion, the division gives 16597.5087108 with a balance of 1.2e-07.
