521651 ÷ 5 
We're looking to find how many times 5 goes into 521651.

Moving on to step 1:
The number 5 fits into 5 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 5 from 5 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 5

On to step 2:
When dividing 2 by 5, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 5

Step 3:
21 divided by 5 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
Subtracting 20 from 21 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 5

Advancing to step 4:
If we divide 16 by 5, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 1043.0
Deduct 15 from 16 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 5

Step 5:
The number 5 fits into 15 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 10433.0
Subtract 15 from 15 to get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 5

On to step 6:
The number 5 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 104330.0
Subtracting 0 from 1 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
5 can be fit into 10 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 104330.2
The remainder is 0 after subtracting 10 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 5, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 104330.2
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
When dividing 0 by 5, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 104330.2
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 104330.2, with a leftover of 0.0.
