We're dividing 53838425 by 521 
We want to figure out the number of times 53838425 can be divided by 521.

Going ahead to step 1:
521 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 521

Step 2:
When dividing 53 by 521, we get 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Append the next digit (8) from the dividend to 53 and continue with: 538 / 521

Advancing to step 3:
When dividing 538 by 521, we get 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 521 away from 538, we end up with 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 521

Advancing to step 4:
If we divide 173 by 521, we get 0 and a remainder of 173.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 173 and we're left with 173.
Take the next digit (8) from the dividend and append it to 173, then repeat: 1738 / 521

Let's proceed to step 5:
When dividing 1738 by 521, we get 3 with a remainder of 175.
Use 3 as the next digit of our solution. 
Result so far: 103.0
If we take 1563 away from 1738, we end up with 175.
Grab the next digit (4) from the dividend, add it to 175, then carry on: 1754 / 521

Advancing to step 6:
1754 divided by 521 is 3 with a remainder of 191.
The next digit of our result is 3. 
Result so far: 1033.0
If we subtract 1563 from 1754, we get 191.
Fetch the next digit (2) from the dividend, attach it to 191 and continue: 1912 / 521

Step 7:
When dividing 1912 by 521, we get 3 with a remainder of 349.
Record the quotient 3 as the next digit in the result. 
Result so far: 10333.0
If we subtract 1563 from 1912, we get 349.
Include the next digit (5) from the dividend after 349, then repeat: 3495 / 521

Advancing to step 8:
521 can be fit into 3495 6 times, resulting in a remainder of 369.
Use 6 as the next digit of our solution. 
Result so far: 103336.0
If we take 3126 away from 3495, we end up with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Let's proceed to step 9:
3690 divided by 521 is 7 with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 103336.7
The remainder is 43 after subtracting 3647 from 3690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 10:
The number 521 fits into 430 0 times, leaving a remainder of 430.
The next digit of our result is 0. 
Result so far: 103336.7
Deduct 0 from 430 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 11:
521 goes into 4300 8 times with a remainder of 132.
Record the quotient 8 as the next digit in the result. 
Result so far: 103336.708
Deduct 4168 from 4300 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 12:
When dividing 1320 by 521, we get 2 with a remainder of 278.
Write down 2 as next digit of the result. 
Result so far: 103336.7082
Subtract 1042 from 1320 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 13:
If we divide 2780 by 521, we get 5 and a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 103336.70825
Subtract 2605 from 2780 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 14:
521 goes into 1750 3 times with a remainder of 187.
The next digit of our result is 3. 
Result so far: 103336.708253
Subtract 1563 from 1750 to get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Going ahead to step 15:
521 goes into 1870 3 times with a remainder of 307.
The next digit of our result is 3. 
Result so far: 103336.7082533
If we subtract 1563 from 1870, we get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

After the division, we end up with 103336.7082533 and a remainder of 3.07e-06.
