842639 ÷ 69 
Our goal is to divide 842639 by 69.

Advancing to step 1:
When dividing 8 by 69, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 69

Step 2:
84 divided by 69 is 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 69 from 84 to get 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 69

On to step 3:
69 goes into 152 2 times with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 138 from 152 and we're left with 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 69

Let's proceed to step 4:
69 goes into 146 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
The remainder is 8 after subtracting 138 from 146.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 69

Let's proceed to step 5:
When dividing 83 by 69, we get 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1221.0
Deduct 69 from 83 and we're left with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 69

Going ahead to step 6:
149 divided by 69 is 2 with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 12212.0
If we subtract 138 from 149, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
110 divided by 69 is 1 with a remainder of 41.
The next digit of our result is 1. 
Result so far: 12212.1
If we take 69 away from 110, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 8:
If we divide 410 by 69, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 12212.15
Subtract 345 from 410 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 9:
69 can be fit into 650 9 times, resulting in a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 12212.159
If we subtract 621 from 650, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 10:
When dividing 290 by 69, we get 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 12212.1594
If we subtract 276 from 290, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
If we divide 140 by 69, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 12212.15942
Subtracting 138 from 140 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
20 divided by 69 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 12212.15942
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
200 divided by 69 is 2 with a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 12212.1594202
If we subtract 138 from 200, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 14:
69 goes into 620 8 times with a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 12212.15942028
If we subtract 552 from 620, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The quotient of the division is 12212.15942028, and the remainder is 6.8e-08.
