45803519 ÷ 159 
We want to divide 45803519 by 159.

Moving on to step 1:
159 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 159

On to step 2:
159 goes into 45 0 times with a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Include the next digit (8) from the dividend after 45, then repeat: 458 / 159

Moving on to step 3:
458 divided by 159 is 2 with a remainder of 140.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 318 from 458 leaves us with 140.
Grab the next digit (0) from the dividend, add it to 140, then carry on: 1400 / 159

Moving on to step 4:
When dividing 1400 by 159, we get 8 with a remainder of 128.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 128 after subtracting 1272 from 1400.
Take the next digit (3) from the dividend and append it to 128, then repeat: 1283 / 159

Let's proceed to step 5:
1283 divided by 159 is 8 with a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 288.0
If we take 1272 away from 1283, we end up with 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 159

Advancing to step 6:
159 can be fit into 115 0 times, resulting in a remainder of 115.
Record the quotient 0 as the next digit in the result. 
Result so far: 2880.0
The remainder is 115 after subtracting 0 from 115.
Take the next digit (1) from the dividend and append it to 115, then repeat: 1151 / 159

Let's proceed to step 7:
159 goes into 1151 7 times with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 28807.0
The remainder is 38 after subtracting 1113 from 1151.
Include the next digit (9) from the dividend after 38, then repeat: 389 / 159

On to step 8:
The number 159 fits into 389 2 times, leaving a remainder of 71.
The next digit of our result is 2. 
Result so far: 288072.0
Subtracting 318 from 389 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 9:
The number 159 fits into 710 4 times, leaving a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 288072.4
If we subtract 636 from 710, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 10:
When dividing 740 by 159, we get 4 with a remainder of 104.
Use 4 as the next digit of our solution. 
Result so far: 288072.44
If we subtract 636 from 740, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final outcome is 288072.44, with a leftover of 0.104.
