12418146 divided by 869 
We want to divide 12418146 by 869.

Advancing to step 1:
When dividing 1 by 869, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 869

Let's proceed to step 2:
869 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 869

Going ahead to step 3:
When dividing 124 by 869, we get 0 with a remainder of 124.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 124 to get 124.
Grab the next digit (1) from the dividend, add it to 124, then carry on: 1241 / 869

Moving on to step 4:
869 can be fit into 1241 1 times, resulting in a remainder of 372.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 869 from 1241 to get 372.
Take the next digit (8) from the dividend and append it to 372, then repeat: 3728 / 869

On to step 5:
When dividing 3728 by 869, we get 4 with a remainder of 252.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 3476 from 3728, we get 252.
Append the next digit (1) from the dividend to 252 and continue with: 2521 / 869

On to step 6:
869 can be fit into 2521 2 times, resulting in a remainder of 783.
Use 2 as the next digit of our solution. 
Result so far: 142.0
If we subtract 1738 from 2521, we get 783.
Fetch the next digit (4) from the dividend, attach it to 783 and continue: 7834 / 869

Let's proceed to step 7:
When dividing 7834 by 869, we get 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 1429.0
Subtract 7821 from 7834 to get 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 869

Going ahead to step 8:
The number 869 fits into 136 0 times, leaving a remainder of 136.
The next digit of our result is 0. 
Result so far: 14290.0
If we subtract 0 from 136, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 9:
1360 divided by 869 is 1 with a remainder of 491.
Record the quotient 1 as the next digit in the result. 
Result so far: 14290.1
Subtract 869 from 1360 to get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Moving on to step 10:
If we divide 4910 by 869, we get 5 and a remainder of 565.
The number 5 becomes the next digit in our result. 
Result so far: 14290.15
Subtracting 4345 from 4910 leaves us with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Step 11:
If we divide 5650 by 869, we get 6 and a remainder of 436.
The number 6 becomes the next digit in our result. 
Result so far: 14290.156
Subtracting 5214 from 5650 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Moving on to step 12:
The number 869 fits into 4360 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 14290.1565
The remainder is 15 after subtracting 4345 from 4360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
869 goes into 150 0 times with a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 14290.1565
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 14:
If we divide 1500 by 869, we get 1 and a remainder of 631.
The number 1 becomes the next digit in our result. 
Result so far: 14290.156501
If we subtract 869 from 1500, we get 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

On to step 15:
When dividing 6310 by 869, we get 7 with a remainder of 227.
The next digit of our result is 7. 
Result so far: 14290.1565017
If we subtract 6083 from 6310, we get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Going ahead to step 16:
When dividing 2270 by 869, we get 2 with a remainder of 532.
The next digit of our result is 2. 
Result so far: 14290.15650172
Deduct 1738 from 2270 and we're left with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

The final outcome is 14290.15650172, with a leftover of 5.32e-07.
