We're dividing 4978015 by 159 
Let's see how many times 159 fits into 4978015.

Step 1:
4 divided by 159 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 159

Going ahead to step 2:
49 divided by 159 is 0 with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 159

Step 3:
If we divide 497 by 159, we get 3 and a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 477 away from 497, we end up with 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 159

Step 4:
When dividing 208 by 159, we get 1 with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Deduct 159 from 208 and we're left with 49.
Take the next digit (0) from the dividend and append it to 49, then repeat: 490 / 159

Moving on to step 5:
159 goes into 490 3 times with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 313.0
Subtracting 477 from 490 leaves us with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 159

Moving on to step 6:
131 divided by 159 is 0 with a remainder of 131.
The number 0 becomes the next digit in our result. 
Result so far: 3130.0
If we take 0 away from 131, we end up with 131.
Append the next digit (5) from the dividend to 131 and continue with: 1315 / 159

Going ahead to step 7:
When dividing 1315 by 159, we get 8 with a remainder of 43.
Use 8 as the next digit of our solution. 
Result so far: 31308.0
If we subtract 1272 from 1315, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 8:
If we divide 430 by 159, we get 2 and a remainder of 112.
Record the quotient 2 as the next digit in the result. 
Result so far: 31308.2
The remainder is 112 after subtracting 318 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 9:
The number 159 fits into 1120 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 31308.27
The remainder is 7 after subtracting 1113 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 10:
70 divided by 159 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 31308.27
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 11:
159 can be fit into 700 4 times, resulting in a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 31308.2704
Subtracting 636 from 700 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
640 divided by 159 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 31308.27044
The remainder is 4 after subtracting 636 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 31308.27044 with a balance of 4e-06.
