We're dividing 17720054 by 345 
Let's see how many times 345 fits into 17720054.

Let's proceed to step 1:
If we divide 1 by 345, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 345

Advancing to step 2:
When dividing 17 by 345, we get 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 345

Step 3:
If we divide 177 by 345, we get 0 and a remainder of 177.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 177, we get 177.
Fetch the next digit (2) from the dividend, attach it to 177 and continue: 1772 / 345

On to step 4:
If we divide 1772 by 345, we get 5 and a remainder of 47.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 1725 from 1772 and we're left with 47.
Grab the next digit (0) from the dividend, add it to 47, then carry on: 470 / 345

Step 5:
The number 345 fits into 470 1 times, leaving a remainder of 125.
The next digit of our result is 1. 
Result so far: 51.0
The remainder is 125 after subtracting 345 from 470.
Take the next digit (0) from the dividend and append it to 125, then repeat: 1250 / 345

Let's proceed to step 6:
1250 divided by 345 is 3 with a remainder of 215.
The next digit of our result is 3. 
Result so far: 513.0
If we take 1035 away from 1250, we end up with 215.
Append the next digit (5) from the dividend to 215 and continue with: 2155 / 345

Going ahead to step 7:
345 goes into 2155 6 times with a remainder of 85.
The number 6 becomes the next digit in our result. 
Result so far: 5136.0
Deduct 2070 from 2155 and we're left with 85.
Append the next digit (4) from the dividend to 85 and continue with: 854 / 345

Let's proceed to step 8:
When dividing 854 by 345, we get 2 with a remainder of 164.
Put 2 as the next digit of the answer. 
Result so far: 51362.0
Subtracting 690 from 854 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 9:
345 goes into 1640 4 times with a remainder of 260.
Write down 4 as next digit of the result. 
Result so far: 51362.4
If we take 1380 away from 1640, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 10:
The number 345 fits into 2600 7 times, leaving a remainder of 185.
The next digit of our result is 7. 
Result so far: 51362.47
Subtracting 2415 from 2600 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 11:
345 can be fit into 1850 5 times, resulting in a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 51362.475
The remainder is 125 after subtracting 1725 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 12:
345 can be fit into 1250 3 times, resulting in a remainder of 215.
Record the quotient 3 as the next digit in the result. 
Result so far: 51362.4753
If we subtract 1035 from 1250, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 13:
When dividing 2150 by 345, we get 6 with a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 51362.47536
If we take 2070 away from 2150, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 14:
800 divided by 345 is 2 with a remainder of 110.
Use 2 as the next digit of our solution. 
Result so far: 51362.475362
The remainder is 110 after subtracting 690 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 15:
1100 divided by 345 is 3 with a remainder of 65.
The next digit of our result is 3. 
Result so far: 51362.4753623
If we subtract 1035 from 1100, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 16:
The number 345 fits into 650 1 times, leaving a remainder of 305.
Put 1 as the next digit of the answer. 
Result so far: 51362.47536231
Subtract 345 from 650 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Our division results in 51362.47536231 with a remaining 3.05e-07.
