We're dividing 12166107 by 860 
Our goal is to divide 12166107 by 860.

Going ahead to step 1:
1 divided by 860 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 860

Moving on to step 2:
The number 860 fits into 12 0 times, leaving a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 860

Let's proceed to step 3:
121 divided by 860 is 0 with a remainder of 121.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 121 leaves us with 121.
Bring next digit (6) of the dividend behind the 121 and repeat the process: 1216 / 860

Moving on to step 4:
860 can be fit into 1216 1 times, resulting in a remainder of 356.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 860 from 1216 and we're left with 356.
Bring next digit (6) of the dividend behind the 356 and repeat the process: 3566 / 860

On to step 5:
The number 860 fits into 3566 4 times, leaving a remainder of 126.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 126 after subtracting 3440 from 3566.
Bring next digit (1) of the dividend behind the 126 and repeat the process: 1261 / 860

Let's proceed to step 6:
860 goes into 1261 1 times with a remainder of 401.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
Subtract 860 from 1261 to get 401.
Take the next digit (0) from the dividend and append it to 401, then repeat: 4010 / 860

Step 7:
860 goes into 4010 4 times with a remainder of 570.
Put 4 as the next digit of the answer. 
Result so far: 1414.0
If we subtract 3440 from 4010, we get 570.
Grab the next digit (7) from the dividend, add it to 570, then carry on: 5707 / 860

On to step 8:
5707 divided by 860 is 6 with a remainder of 547.
The number 6 becomes the next digit in our result. 
Result so far: 14146.0
The remainder is 547 after subtracting 5160 from 5707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Going ahead to step 9:
When dividing 5470 by 860, we get 6 with a remainder of 310.
Put 6 as the next digit of the answer. 
Result so far: 14146.6
Subtract 5160 from 5470 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 10:
3100 divided by 860 is 3 with a remainder of 520.
Record the quotient 3 as the next digit in the result. 
Result so far: 14146.63
Subtracting 2580 from 3100 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 11:
The number 860 fits into 5200 6 times, leaving a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 14146.636
The remainder is 40 after subtracting 5160 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
If we divide 400 by 860, we get 0 and a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 14146.636
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 13:
860 can be fit into 4000 4 times, resulting in a remainder of 560.
Put 4 as the next digit of the answer. 
Result so far: 14146.63604
The remainder is 560 after subtracting 3440 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 14:
860 goes into 5600 6 times with a remainder of 440.
Use 6 as the next digit of our solution. 
Result so far: 14146.636046
Subtract 5160 from 5600 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 15:
860 goes into 4400 5 times with a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 14146.6360465
If we take 4300 away from 4400, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 16:
860 can be fit into 1000 1 times, resulting in a remainder of 140.
Write down 1 as next digit of the result. 
Result so far: 14146.63604651
Subtract 860 from 1000 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Our division results in 14146.63604651 with a remaining 1.4e-07.
