421215 ÷ 69 
We're looking to find how many times 69 goes into 421215.

Moving on to step 1:
If we divide 4 by 69, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 69

Moving on to step 2:
69 goes into 42 0 times with 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.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 69

Going ahead to step 3:
69 goes into 421 6 times with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 7 after subtracting 414 from 421.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 69

Let's proceed to step 4:
72 divided by 69 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 61.0
Subtract 69 from 72 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 69

Moving on to step 5:
69 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 610.0
If we subtract 0 from 31, we get 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 69

Let's proceed to step 6:
If we divide 315 by 69, we get 4 and a remainder of 39.
The next digit of our result is 4. 
Result so far: 6104.0
The remainder is 39 after subtracting 276 from 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
When dividing 390 by 69, we get 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 6104.5
Subtracting 345 from 390 leaves us 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.

On to step 8:
69 goes into 450 6 times with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 6104.56
Subtract 414 from 450 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
69 can be fit into 360 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 6104.565
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:
150 divided by 69 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 6104.5652
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.

Going ahead to step 11:
If we divide 120 by 69, we get 1 and a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 6104.56521
If we take 69 away from 120, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 12:
69 goes into 510 7 times with a remainder of 27.
The next digit of our result is 7. 
Result so far: 6104.565217
Subtract 483 from 510 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 13:
When dividing 270 by 69, we get 3 with a remainder of 63.
The next digit of our result is 3. 
Result so far: 6104.5652173
Deduct 207 from 270 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 14:
69 can be fit into 630 9 times, resulting in a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 6104.56521739
If we take 621 away from 630, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Our division results in 6104.56521739 with a remaining 9e-09.
