49593559 ÷ 521 
The aim is to understand the frequency of 521 in 49593559.

Advancing to step 1:
521 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 521

Step 2:
The number 521 fits into 49 0 times, leaving a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Fetch the next digit (5) from the dividend, attach it to 49 and continue: 495 / 521

Moving on to step 3:
521 can be fit into 495 0 times, resulting in a remainder of 495.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 495, we end up with 495.
Fetch the next digit (9) from the dividend, attach it to 495 and continue: 4959 / 521

On to step 4:
The number 521 fits into 4959 9 times, leaving a remainder of 270.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 4689 from 4959 to get 270.
Take the next digit (3) from the dividend and append it to 270, then repeat: 2703 / 521

Advancing to step 5:
521 goes into 2703 5 times with a remainder of 98.
Write down 5 as next digit of the result. 
Result so far: 95.0
If we take 2605 away from 2703, we end up with 98.
Append the next digit (5) from the dividend to 98 and continue with: 985 / 521

On to step 6:
The number 521 fits into 985 1 times, leaving a remainder of 464.
Use 1 as the next digit of our solution. 
Result so far: 951.0
Subtracting 521 from 985 leaves us with 464.
Take the next digit (5) from the dividend and append it to 464, then repeat: 4645 / 521

Let's proceed to step 7:
If we divide 4645 by 521, we get 8 and a remainder of 477.
Use 8 as the next digit of our solution. 
Result so far: 9518.0
Subtract 4168 from 4645 to get 477.
Take the next digit (9) from the dividend and append it to 477, then repeat: 4779 / 521

Let's proceed to step 8:
If we divide 4779 by 521, we get 9 and a remainder of 90.
The next digit of our result is 9. 
Result so far: 95189.0
Deduct 4689 from 4779 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 9:
521 can be fit into 900 1 times, resulting in a remainder of 379.
The number 1 becomes the next digit in our result. 
Result so far: 95189.1
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.

Step 10:
If we divide 3790 by 521, we get 7 and a remainder of 143.
Write down 7 as next digit of the result. 
Result so far: 95189.17
The remainder is 143 after subtracting 3647 from 3790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Advancing to step 11:
1430 divided by 521 is 2 with a remainder of 388.
The number 2 becomes the next digit in our result. 
Result so far: 95189.172
If we subtract 1042 from 1430, we get 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 12:
The number 521 fits into 3880 7 times, leaving a remainder of 233.
Write down 7 as next digit of the result. 
Result so far: 95189.1727
If we take 3647 away from 3880, we end up 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.

Going ahead to step 13:
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: 95189.17274
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 14:
2460 divided by 521 is 4 with a remainder of 376.
Put 4 as the next digit of the answer. 
Result so far: 95189.172744
Subtract 2084 from 2460 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

The quotient of the division is 95189.172744, and the remainder is 3.76e-05.
