63809219 ÷ 345 
We want to divide 63809219 by 345.

Going ahead to step 1:
The number 345 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 345

Advancing to step 2:
When dividing 63 by 345, we get 0 with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 345

Let's proceed to step 3:
345 goes into 638 1 times with a remainder of 293.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 345 from 638 to get 293.
Take the next digit (0) from the dividend and append it to 293, then repeat: 2930 / 345

On to step 4:
345 goes into 2930 8 times with a remainder of 170.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 170 after subtracting 2760 from 2930.
Fetch the next digit (9) from the dividend, attach it to 170 and continue: 1709 / 345

Moving on to step 5:
When dividing 1709 by 345, we get 4 with a remainder of 329.
Use 4 as the next digit of our solution. 
Result so far: 184.0
Deduct 1380 from 1709 and we're left with 329.
Grab the next digit (2) from the dividend, add it to 329, then carry on: 3292 / 345

On to step 6:
3292 divided by 345 is 9 with a remainder of 187.
The number 9 becomes the next digit in our result. 
Result so far: 1849.0
If we subtract 3105 from 3292, we get 187.
Take the next digit (1) from the dividend and append it to 187, then repeat: 1871 / 345

Let's proceed to step 7:
345 goes into 1871 5 times with a remainder of 146.
The next digit of our result is 5. 
Result so far: 18495.0
Subtract 1725 from 1871 to get 146.
Append the next digit (9) from the dividend to 146 and continue with: 1469 / 345

Moving on to step 8:
When dividing 1469 by 345, we get 4 with a remainder of 89.
Record the quotient 4 as the next digit in the result. 
Result so far: 184954.0
Subtracting 1380 from 1469 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 9:
The number 345 fits into 890 2 times, leaving a remainder of 200.
Use 2 as the next digit of our solution. 
Result so far: 184954.2
The remainder is 200 after subtracting 690 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 10:
The number 345 fits into 2000 5 times, leaving a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 184954.25
If we take 1725 away from 2000, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 11:
345 goes into 2750 7 times with a remainder of 335.
Use 7 as the next digit of our solution. 
Result so far: 184954.257
Subtracting 2415 from 2750 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Step 12:
If we divide 3350 by 345, we get 9 and a remainder of 245.
Write down 9 as next digit of the result. 
Result so far: 184954.2579
Subtract 3105 from 3350 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 13:
345 goes into 2450 7 times with a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 184954.25797
Deduct 2415 from 2450 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 14:
The number 345 fits into 350 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 184954.257971
The remainder is 5 after subtracting 345 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 15:
345 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 184954.257971
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 16:
When dividing 500 by 345, we get 1 with a remainder of 155.
Record the quotient 1 as the next digit in the result. 
Result so far: 184954.25797101
The remainder is 155 after subtracting 345 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

The final outcome is 184954.25797101, with a leftover of 1.55e-07.
