Let's divide 312126 by 69
We want to divide 312126 by 69.

Going ahead to step 1:
If we divide 3 by 69, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 69

Advancing to step 2:
If we divide 31 by 69, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 69

On to step 3:
When dividing 312 by 69, we get 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 276 from 312, we get 36.
Grab the next digit (1) from the dividend, add it to 36, then carry on: 361 / 69

Step 4:
When dividing 361 by 69, we get 5 with a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
If we subtract 345 from 361, we get 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 69

Moving on to step 5:
If we divide 162 by 69, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 452.0
If we take 138 away from 162, we end up with 24.
Take the next digit (6) from the dividend and append it to 24, then repeat: 246 / 69

On to step 6:
246 divided by 69 is 3 with a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 4523.0
Subtract 207 from 246 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 7:
69 goes into 390 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 4523.5
If we subtract 345 from 390, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 8:
69 can be fit into 450 6 times, resulting in a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 4523.56
If we take 414 away from 450, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
69 goes into 360 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 4523.565
If we subtract 345 from 360, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
If we divide 150 by 69, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 4523.5652
The remainder is 12 after subtracting 138 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
If we divide 120 by 69, we get 1 and a remainder of 51.
The next digit of our result is 1. 
Result so far: 4523.56521
The remainder is 51 after subtracting 69 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 12:
69 goes into 510 7 times with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 4523.565217
Subtracting 483 from 510 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 13:
69 goes into 270 3 times with a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 4523.5652173
The remainder is 63 after subtracting 207 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 14:
When dividing 630 by 69, we get 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 4523.56521739
The remainder is 9 after subtracting 621 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 4523.56521739 with a balance of 9e-09.
