725858 ÷ 53 
We're looking to find how many times 53 goes into 725858.

Advancing to step 1:
When dividing 7 by 53, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 53

Going ahead to step 2:
If we divide 72 by 53, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 19 after subtracting 53 from 72.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 53

Advancing to step 3:
The number 53 fits into 195 3 times, leaving a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 36 after subtracting 159 from 195.
Append the next digit (8) from the dividend to 36 and continue with: 368 / 53

Step 4:
53 goes into 368 6 times with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 136.0
Subtract 318 from 368 to get 50.
Grab the next digit (5) from the dividend, add it to 50, then carry on: 505 / 53

Going ahead to step 5:
53 goes into 505 9 times with a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 1369.0
Subtract 477 from 505 to get 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 53

Let's proceed to step 6:
The number 53 fits into 288 5 times, leaving a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 13695.0
If we take 265 away from 288, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
53 can be fit into 230 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 13695.4
Deduct 212 from 230 and we're left 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.

On to step 8:
53 can be fit into 180 3 times, resulting in a remainder of 21.
The next digit of our result is 3. 
Result so far: 13695.43
Subtracting 159 from 180 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
If we divide 210 by 53, we get 3 and a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 13695.433
The remainder is 51 after subtracting 159 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 13695.433, with a leftover of 0.0051.
