We divide 71781826 by 521
Our goal is to divide 71781826 by 521.

Let's proceed to step 1:
521 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 521

Let's proceed to step 2:
When dividing 71 by 521, we get 0 with a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Fetch the next digit (7) from the dividend, attach it to 71 and continue: 717 / 521

Going ahead to step 3:
If we divide 717 by 521, we get 1 and a remainder of 196.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 521 from 717 to get 196.
Fetch the next digit (8) from the dividend, attach it to 196 and continue: 1968 / 521

Advancing to step 4:
When dividing 1968 by 521, we get 3 with a remainder of 405.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 1563 from 1968 and we're left with 405.
Take the next digit (1) from the dividend and append it to 405, then repeat: 4051 / 521

Going ahead to step 5:
The number 521 fits into 4051 7 times, leaving a remainder of 404.
Put 7 as the next digit of the answer. 
Result so far: 137.0
Subtracting 3647 from 4051 leaves us with 404.
Include the next digit (8) from the dividend after 404, then repeat: 4048 / 521

Moving on to step 6:
When dividing 4048 by 521, we get 7 with a remainder of 401.
The next digit of our result is 7. 
Result so far: 1377.0
Deduct 3647 from 4048 and we're left with 401.
Fetch the next digit (2) from the dividend, attach it to 401 and continue: 4012 / 521

On to step 7:
If we divide 4012 by 521, we get 7 and a remainder of 365.
The number 7 becomes the next digit in our result. 
Result so far: 13777.0
Deduct 3647 from 4012 and we're left with 365.
Include the next digit (6) from the dividend after 365, then repeat: 3656 / 521

Step 8:
When dividing 3656 by 521, we get 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 137777.0
If we subtract 3647 from 3656, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
The number 521 fits into 90 0 times, leaving a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 137777.0
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 10:
900 divided by 521 is 1 with a remainder of 379.
Write down 1 as next digit of the result. 
Result so far: 137777.01
Subtract 521 from 900 to get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Let's proceed to step 11:
When dividing 3790 by 521, we get 7 with a remainder of 143.
Use 7 as the next digit of our solution. 
Result so far: 137777.017
Subtracting 3647 from 3790 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Step 12:
When dividing 1430 by 521, we get 2 with a remainder of 388.
Use 2 as the next digit of our solution. 
Result so far: 137777.0172
If we take 1042 away from 1430, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Going ahead to step 13:
521 can be fit into 3880 7 times, resulting in a remainder of 233.
Use 7 as the next digit of our solution. 
Result so far: 137777.01727
Subtracting 3647 from 3880 leaves us with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Moving on to step 14:
521 goes into 2330 4 times with a remainder of 246.
Record the quotient 4 as the next digit in the result. 
Result so far: 137777.017274
If we take 2084 away from 2330, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 15:
The number 521 fits into 2460 4 times, leaving a remainder of 376.
Put 4 as the next digit of the answer. 
Result so far: 137777.0172744
If we take 2084 away from 2460, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

After the division, we end up with 137777.0172744 and a remainder of 3.76e-06.
