We're dividing 215994 by 58 
We want to figure out the number of times 215994 can be divided by 58.

On to step 1:
The number 58 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 58

Let's proceed to step 2:
If we divide 21 by 58, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 58

On to step 3:
58 goes into 215 3 times with a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 174 from 215 leaves us with 41.
Append the next digit (9) from the dividend to 41 and continue with: 419 / 58

Step 4:
When dividing 419 by 58, we get 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtract 406 from 419 to get 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 58

Advancing to step 5:
If we divide 139 by 58, we get 2 and a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 372.0
Deduct 116 from 139 and we're left with 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 58

Moving on to step 6:
58 goes into 234 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 3724.0
If we take 232 away from 234, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
58 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 3724.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
If we divide 200 by 58, we get 3 and a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 3724.03
Deduct 174 from 200 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
58 can be fit into 260 4 times, resulting in a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 3724.034
If we take 232 away from 260, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
58 can be fit into 280 4 times, resulting in a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 3724.0344
The remainder is 48 after subtracting 232 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 3724.0344 with a remaining 0.00048.
