We're dividing 54531789 by 345 
We want to figure out the number of times 54531789 can be divided by 345.

Going ahead to step 1:
345 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 345

Moving on to step 2:
When dividing 54 by 345, we get 0 with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Include the next digit (5) from the dividend after 54, then repeat: 545 / 345

Step 3:
345 can be fit into 545 1 times, resulting in a remainder of 200.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 345 from 545 leaves us with 200.
Bring next digit (3) of the dividend behind the 200 and repeat the process: 2003 / 345

Advancing to step 4:
345 can be fit into 2003 5 times, resulting in a remainder of 278.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 1725 away from 2003, we end up with 278.
Include the next digit (1) from the dividend after 278, then repeat: 2781 / 345

Step 5:
If we divide 2781 by 345, we get 8 and a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
If we take 2760 away from 2781, we end up with 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 345

Let's proceed to step 6:
345 can be fit into 217 0 times, resulting in a remainder of 217.
Write down 0 as next digit of the result. 
Result so far: 1580.0
The remainder is 217 after subtracting 0 from 217.
Append the next digit (8) from the dividend to 217 and continue with: 2178 / 345

On to step 7:
345 can be fit into 2178 6 times, resulting in a remainder of 108.
Use 6 as the next digit of our solution. 
Result so far: 15806.0
Deduct 2070 from 2178 and we're left with 108.
Include the next digit (9) from the dividend after 108, then repeat: 1089 / 345

Let's proceed to step 8:
345 can be fit into 1089 3 times, resulting in a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 158063.0
If we subtract 1035 from 1089, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 9:
When dividing 540 by 345, we get 1 with a remainder of 195.
The number 1 becomes the next digit in our result. 
Result so far: 158063.1
If we take 345 away from 540, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Advancing to step 10:
If we divide 1950 by 345, we get 5 and a remainder of 225.
Put 5 as the next digit of the answer. 
Result so far: 158063.15
If we take 1725 away from 1950, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 11:
345 can be fit into 2250 6 times, resulting in a remainder of 180.
The number 6 becomes the next digit in our result. 
Result so far: 158063.156
Subtract 2070 from 2250 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 12:
1800 divided by 345 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 158063.1565
If we take 1725 away from 1800, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 13:
The number 345 fits into 750 2 times, leaving a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 158063.15652
Subtract 690 from 750 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
345 goes into 600 1 times with a remainder of 255.
Put 1 as the next digit of the answer. 
Result so far: 158063.156521
If we subtract 345 from 600, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 15:
2550 divided by 345 is 7 with a remainder of 135.
The next digit of our result is 7. 
Result so far: 158063.1565217
The remainder is 135 after subtracting 2415 from 2550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 16:
If we divide 1350 by 345, we get 3 and a remainder of 315.
Record the quotient 3 as the next digit in the result. 
Result so far: 158063.15652173
Deduct 1035 from 1350 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

In conclusion, the division gives 158063.15652173 with a balance of 3.15e-07.
