We look at the division of 721312 by 58 
We want to divide 721312 by 58.

Advancing to step 1:
58 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 58

Going ahead to step 2:
58 can be fit into 72 1 times, resulting in a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 58 from 72 to get 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 58

Step 3:
58 can be fit into 141 2 times, resulting in a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 116 away from 141, we end up with 25.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 58

On to step 4:
58 goes into 253 4 times with a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 124.0
Subtract 232 from 253 to get 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 58

Step 5:
58 goes into 211 3 times with a remainder of 37.
The next digit of our result is 3. 
Result so far: 1243.0
If we take 174 away from 211, we end up with 37.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 58

Advancing to step 6:
58 goes into 372 6 times with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 12436.0
Subtract 348 from 372 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
If we divide 240 by 58, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 12436.4
Deduct 232 from 240 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
58 can be fit into 80 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 12436.41
Subtracting 58 from 80 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
The number 58 fits into 220 3 times, leaving a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 12436.413
Deduct 174 from 220 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
The number 58 fits into 460 7 times, leaving a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 12436.4137
Subtracting 406 from 460 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 11:
The number 58 fits into 540 9 times, leaving a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 12436.41379
If we take 522 away from 540, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
The number 58 fits into 180 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 12436.413793
Subtracting 174 from 180 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
58 goes into 60 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 12436.4137931
Subtract 58 from 60 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 14:
58 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 12436.4137931
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.

The final result is 12436.4137931 with a remainder of 2e-08.
