We look at the division of 64469148 by 521 
Let's see how many times 521 fits into 64469148.

Going ahead to step 1:
If we divide 6 by 521, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 521

Step 2:
521 goes into 64 0 times with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 521

Going ahead to step 3:
If we divide 644 by 521, we get 1 and a remainder of 123.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 521 from 644 to get 123.
Take the next digit (6) from the dividend and append it to 123, then repeat: 1236 / 521

Moving on to step 4:
If we divide 1236 by 521, we get 2 and a remainder of 194.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 1042 from 1236 leaves us with 194.
Include the next digit (9) from the dividend after 194, then repeat: 1949 / 521

Step 5:
521 goes into 1949 3 times with a remainder of 386.
Use 3 as the next digit of our solution. 
Result so far: 123.0
If we take 1563 away from 1949, we end up with 386.
Take the next digit (1) from the dividend and append it to 386, then repeat: 3861 / 521

Step 6:
521 goes into 3861 7 times with a remainder of 214.
Use 7 as the next digit of our solution. 
Result so far: 1237.0
The remainder is 214 after subtracting 3647 from 3861.
Grab the next digit (4) from the dividend, add it to 214, then carry on: 2144 / 521

On to step 7:
If we divide 2144 by 521, we get 4 and a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 12374.0
The remainder is 60 after subtracting 2084 from 2144.
Take the next digit (8) from the dividend and append it to 60, then repeat: 608 / 521

Advancing to step 8:
The number 521 fits into 608 1 times, leaving a remainder of 87.
Record the quotient 1 as the next digit in the result. 
Result so far: 123741.0
Deduct 521 from 608 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 9:
When dividing 870 by 521, we get 1 with a remainder of 349.
Write down 1 as next digit of the result. 
Result so far: 123741.1
The remainder is 349 after subtracting 521 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Step 10:
The number 521 fits into 3490 6 times, leaving a remainder of 364.
Put 6 as the next digit of the answer. 
Result so far: 123741.16
If we subtract 3126 from 3490, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 11:
If we divide 3640 by 521, we get 6 and a remainder of 514.
Use 6 as the next digit of our solution. 
Result so far: 123741.166
Subtracting 3126 from 3640 leaves us with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

The quotient of the division is 123741.166, and the remainder is 0.0514.
