We divide 345221 by 407
Let's see how many times 407 fits into 345221.

Moving on to step 1:
When dividing 3 by 407, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 407

Moving on to step 2:
407 goes into 34 0 times with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 407

Moving on to step 3:
345 divided by 407 is 0 with a remainder of 345.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 345 to get 345.
Grab the next digit (2) from the dividend, add it to 345, then carry on: 3452 / 407

Advancing to step 4:
407 goes into 3452 8 times with a remainder of 196.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 3256 from 3452 leaves us with 196.
Grab the next digit (2) from the dividend, add it to 196, then carry on: 1962 / 407

Moving on to step 5:
If we divide 1962 by 407, we get 4 and a remainder of 334.
Use 4 as the next digit of our solution. 
Result so far: 84.0
If we take 1628 away from 1962, we end up with 334.
Append the next digit (1) from the dividend to 334 and continue with: 3341 / 407

Let's proceed to step 6:
If we divide 3341 by 407, we get 8 and a remainder of 85.
Write down 8 as next digit of the result. 
Result so far: 848.0
If we subtract 3256 from 3341, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 7:
If we divide 850 by 407, we get 2 and a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 848.2
Deduct 814 from 850 and we're left with 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 8:
360 divided by 407 is 0 with a remainder of 360.
The number 0 becomes the next digit in our result. 
Result so far: 848.2
Deduct 0 from 360 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 9:
The number 407 fits into 3600 8 times, leaving a remainder of 344.
Put 8 as the next digit of the answer. 
Result so far: 848.208
Subtract 3256 from 3600 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 10:
407 can be fit into 3440 8 times, resulting in a remainder of 184.
The next digit of our result is 8. 
Result so far: 848.2088
If we subtract 3256 from 3440, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The final outcome is 848.2088, with a leftover of 0.00184.
