We're dividing 235489 by 621 
We're looking to find how many times 621 goes into 235489.

Moving on to step 1:
The number 621 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 621

On to step 2:
When dividing 23 by 621, we get 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 621

Moving on to step 3:
235 divided by 621 is 0 with a remainder of 235.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 235 and we're left with 235.
Append the next digit (4) from the dividend to 235 and continue with: 2354 / 621

Step 4:
If we divide 2354 by 621, we get 3 and a remainder of 491.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 1863 from 2354 leaves us with 491.
Take the next digit (8) from the dividend and append it to 491, then repeat: 4918 / 621

Advancing to step 5:
If we divide 4918 by 621, we get 7 and a remainder of 571.
The next digit of our result is 7. 
Result so far: 37.0
Deduct 4347 from 4918 and we're left with 571.
Grab the next digit (9) from the dividend, add it to 571, then carry on: 5719 / 621

Advancing to step 6:
621 goes into 5719 9 times with a remainder of 130.
The next digit of our result is 9. 
Result so far: 379.0
If we take 5589 away from 5719, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 7:
621 goes into 1300 2 times with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 379.2
Deduct 1242 from 1300 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 8:
580 divided by 621 is 0 with a remainder of 580.
Use 0 as the next digit of our solution. 
Result so far: 379.2
Subtracting 0 from 580 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 9:
If we divide 5800 by 621, we get 9 and a remainder of 211.
Put 9 as the next digit of the answer. 
Result so far: 379.209
If we subtract 5589 from 5800, we get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 10:
621 goes into 2110 3 times with a remainder of 247.
Put 3 as the next digit of the answer. 
Result so far: 379.2093
The remainder is 247 after subtracting 1863 from 2110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Moving on to step 11:
2470 divided by 621 is 3 with a remainder of 607.
Put 3 as the next digit of the answer. 
Result so far: 379.20933
Deduct 1863 from 2470 and we're left with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

The final outcome is 379.20933, with a leftover of 0.000607.
