422929 ÷ 869 
We want to figure out the number of times 422929 can be divided by 869.

Step 1:
If we divide 4 by 869, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 869

Advancing to step 2:
869 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (2) from the dividend and append it to 42, then repeat: 422 / 869

Going ahead to step 3:
869 can be fit into 422 0 times, resulting in a remainder of 422.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 422 after subtracting 0 from 422.
Include the next digit (9) from the dividend after 422, then repeat: 4229 / 869

Going ahead to step 4:
If we divide 4229 by 869, we get 4 and a remainder of 753.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 753 after subtracting 3476 from 4229.
Include the next digit (2) from the dividend after 753, then repeat: 7532 / 869

On to step 5:
869 can be fit into 7532 8 times, resulting in a remainder of 580.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
If we take 6952 away from 7532, we end up with 580.
Fetch the next digit (9) from the dividend, attach it to 580 and continue: 5809 / 869

Moving on to step 6:
If we divide 5809 by 869, we get 6 and a remainder of 595.
The next digit of our result is 6. 
Result so far: 486.0
If we take 5214 away from 5809, we end up with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Moving on to step 7:
The number 869 fits into 5950 6 times, leaving a remainder of 736.
The next digit of our result is 6. 
Result so far: 486.6
Subtracting 5214 from 5950 leaves us with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Advancing to step 8:
If we divide 7360 by 869, we get 8 and a remainder of 408.
Write down 8 as next digit of the result. 
Result so far: 486.68
If we take 6952 away from 7360, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Let's proceed to step 9:
If we divide 4080 by 869, we get 4 and a remainder of 604.
Record the quotient 4 as the next digit in the result. 
Result so far: 486.684
If we subtract 3476 from 4080, we get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

On to step 10:
The number 869 fits into 6040 6 times, leaving a remainder of 826.
The number 6 becomes the next digit in our result. 
Result so far: 486.6846
Subtract 5214 from 6040 to get 826.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8260, and continue the process.

On to step 11:
869 can be fit into 8260 9 times, resulting in a remainder of 439.
The next digit of our result is 9. 
Result so far: 486.68469
Subtracting 7821 from 8260 leaves us with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

On to step 12:
The number 869 fits into 4390 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 486.684695
If we take 4345 away from 4390, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 13:
869 can be fit into 450 0 times, resulting in a remainder of 450.
Use 0 as the next digit of our solution. 
Result so far: 486.684695
Subtract 0 from 450 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 14:
When dividing 4500 by 869, we get 5 with a remainder of 155.
The number 5 becomes the next digit in our result. 
Result so far: 486.68469505
Deduct 4345 from 4500 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

The quotient of the division is 486.68469505, and the remainder is 1.55e-07.
