We look at the division of 67410556 by 521 
Our goal is to divide 67410556 by 521.

Moving on to step 1:
521 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 521

Moving on to step 2:
521 goes into 67 0 times with a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Bring next digit (4) of the dividend behind the 67 and repeat the process: 674 / 521

Step 3:
521 can be fit into 674 1 times, resulting in a remainder of 153.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 153 after subtracting 521 from 674.
Take the next digit (1) from the dividend and append it to 153, then repeat: 1531 / 521

Step 4:
If we divide 1531 by 521, we get 2 and a remainder of 489.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 1042 from 1531, we get 489.
Append the next digit (0) from the dividend to 489 and continue with: 4890 / 521

On to step 5:
When dividing 4890 by 521, we get 9 with a remainder of 201.
Use 9 as the next digit of our solution. 
Result so far: 129.0
Subtract 4689 from 4890 to get 201.
Include the next digit (5) from the dividend after 201, then repeat: 2015 / 521

Step 6:
If we divide 2015 by 521, we get 3 and a remainder of 452.
The next digit of our result is 3. 
Result so far: 1293.0
If we take 1563 away from 2015, we end up with 452.
Bring next digit (5) of the dividend behind the 452 and repeat the process: 4525 / 521

On to step 7:
521 goes into 4525 8 times with a remainder of 357.
Record the quotient 8 as the next digit in the result. 
Result so far: 12938.0
The remainder is 357 after subtracting 4168 from 4525.
Include the next digit (6) from the dividend after 357, then repeat: 3576 / 521

On to step 8:
If we divide 3576 by 521, we get 6 and a remainder of 450.
Record the quotient 6 as the next digit in the result. 
Result so far: 129386.0
If we subtract 3126 from 3576, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 9:
If we divide 4500 by 521, we get 8 and a remainder of 332.
Put 8 as the next digit of the answer. 
Result so far: 129386.8
If we take 4168 away from 4500, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Step 10:
When dividing 3320 by 521, we get 6 with a remainder of 194.
The next digit of our result is 6. 
Result so far: 129386.86
If we take 3126 away from 3320, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

On to step 11:
The number 521 fits into 1940 3 times, leaving a remainder of 377.
Write down 3 as next digit of the result. 
Result so far: 129386.863
If we subtract 1563 from 1940, we get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Advancing to step 12:
The number 521 fits into 3770 7 times, leaving a remainder of 123.
Put 7 as the next digit of the answer. 
Result so far: 129386.8637
If we subtract 3647 from 3770, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 13:
521 can be fit into 1230 2 times, resulting in a remainder of 188.
The next digit of our result is 2. 
Result so far: 129386.86372
Subtract 1042 from 1230 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 14:
The number 521 fits into 1880 3 times, leaving a remainder of 317.
Record the quotient 3 as the next digit in the result. 
Result so far: 129386.863723
Deduct 1563 from 1880 and we're left with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Let's proceed to step 15:
521 can be fit into 3170 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 129386.8637236
If we subtract 3126 from 3170, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 16:
521 can be fit into 440 0 times, resulting in a remainder of 440.
Put 0 as the next digit of the answer. 
Result so far: 129386.8637236
Subtract 0 from 440 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The final result is 129386.8637236 with a remainder of 4.4e-07.
