We divide 52475097 by 521
We want to divide 52475097 by 521.

Step 1:
521 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 521

Advancing to step 2:
When dividing 52 by 521, we get 0 with a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Take the next digit (4) from the dividend and append it to 52, then repeat: 524 / 521

Moving on to step 3:
524 divided by 521 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 521 from 524 and we're left with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 521

On to step 4:
When dividing 37 by 521, we get 0 with a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 37 to get 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 521

Step 5:
If we divide 375 by 521, we get 0 and a remainder of 375.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Deduct 0 from 375 and we're left with 375.
Take the next digit (0) from the dividend and append it to 375, then repeat: 3750 / 521

On to step 6:
3750 divided by 521 is 7 with a remainder of 103.
The next digit of our result is 7. 
Result so far: 1007.0
Subtract 3647 from 3750 to get 103.
Fetch the next digit (9) from the dividend, attach it to 103 and continue: 1039 / 521

Let's proceed to step 7:
When dividing 1039 by 521, we get 1 with a remainder of 518.
Put 1 as the next digit of the answer. 
Result so far: 10071.0
Subtract 521 from 1039 to get 518.
Bring next digit (7) of the dividend behind the 518 and repeat the process: 5187 / 521

Advancing to step 8:
5187 divided by 521 is 9 with a remainder of 498.
Record the quotient 9 as the next digit in the result. 
Result so far: 100719.0
Deduct 4689 from 5187 and we're left with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

On to step 9:
When dividing 4980 by 521, we get 9 with a remainder of 291.
The number 9 becomes the next digit in our result. 
Result so far: 100719.9
If we take 4689 away from 4980, we end up with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Step 10:
If we divide 2910 by 521, we get 5 and a remainder of 305.
Write down 5 as next digit of the result. 
Result so far: 100719.95
If we subtract 2605 from 2910, we get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 11:
If we divide 3050 by 521, we get 5 and a remainder of 445.
Record the quotient 5 as the next digit in the result. 
Result so far: 100719.955
If we subtract 2605 from 3050, we get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

After the division, we end up with 100719.955 and a remainder of 0.0445.
