We're dividing 120359 by 58 
Let's see how many times 58 fits into 120359.

Going ahead to step 1:
The number 58 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 58

Going ahead to step 2:
12 divided by 58 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 58

On to step 3:
58 can be fit into 120 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 4 after subtracting 116 from 120.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 58

On to step 4:
58 goes into 43 0 times with a remainder of 43.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 43, we end up with 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 58

Step 5:
The number 58 fits into 435 7 times, leaving a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 207.0
The remainder is 29 after subtracting 406 from 435.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 58

On to step 6:
The number 58 fits into 299 5 times, leaving a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 2075.0
The remainder is 9 after subtracting 290 from 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
If we divide 90 by 58, we get 1 and a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 2075.1
If we subtract 58 from 90, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 8:
320 divided by 58 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 2075.15
If we subtract 290 from 320, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
If we divide 300 by 58, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 2075.155
Deduct 290 from 300 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 2075.155, and the remainder is 0.001.
