421499 ÷ 69 
We want to divide 421499 by 69.

On to step 1:
When dividing 4 by 69, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 69

Let's proceed to step 2:
The number 69 fits into 42 0 times, leaving a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 69

Advancing to step 3:
When dividing 421 by 69, we get 6 with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 414 from 421 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 69

Step 4:
74 divided by 69 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 61.0
Deduct 69 from 74 and we're left with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 69

Step 5:
69 can be fit into 59 0 times, resulting in a remainder of 59.
The next digit of our result is 0. 
Result so far: 610.0
If we subtract 0 from 59, we get 59.
Fetch the next digit (9) from the dividend, attach it to 59 and continue: 599 / 69

On to step 6:
69 goes into 599 8 times with a remainder of 47.
Record the quotient 8 as the next digit in the result. 
Result so far: 6108.0
If we subtract 552 from 599, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 7:
69 goes into 470 6 times with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 6108.6
Subtracting 414 from 470 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 8:
560 divided by 69 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 6108.68
Subtracting 552 from 560 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
When dividing 80 by 69, we get 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 6108.681
The remainder is 11 after subtracting 69 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
69 goes into 110 1 times with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 6108.6811
The remainder is 41 after subtracting 69 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final outcome is 6108.6811, with a leftover of 0.00041.
