We're dividing 866197 by 69 
Our goal is to divide 866197 by 69.

Moving on to step 1:
The number 69 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 69

Moving on to step 2:
69 goes into 86 1 times with a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 17 after subtracting 69 from 86.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 69

Going ahead to step 3:
69 goes into 176 2 times with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 138 away from 176, we end up with 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 69

Moving on to step 4:
The number 69 fits into 381 5 times, leaving a remainder of 36.
Write down 5 as next digit of the result. 
Result so far: 125.0
Deduct 345 from 381 and we're left with 36.
Grab the next digit (9) from the dividend, add it to 36, then carry on: 369 / 69

Going ahead to step 5:
369 divided by 69 is 5 with a remainder of 24.
Record the quotient 5 as the next digit in the result. 
Result so far: 1255.0
If we take 345 away from 369, we end up with 24.
Append the next digit (7) from the dividend to 24 and continue with: 247 / 69

Moving on to step 6:
If we divide 247 by 69, we get 3 and a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 12553.0
If we subtract 207 from 247, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
400 divided by 69 is 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 12553.5
Subtract 345 from 400 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 8:
69 can be fit into 550 7 times, resulting in a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 12553.57
If we subtract 483 from 550, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 9:
69 goes into 670 9 times with a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 12553.579
The remainder is 49 after subtracting 621 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 10:
69 goes into 490 7 times with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 12553.5797
Subtract 483 from 490 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 11:
The number 69 fits into 70 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 12553.57971
If we take 69 away from 70, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
The number 69 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 12553.57971
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
If we divide 100 by 69, we get 1 and a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 12553.5797101
If we take 69 away from 100, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 14:
310 divided by 69 is 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 12553.57971014
If we take 276 away from 310, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 12553.57971014 with a remainder of 3.4e-08.
