Let's divide 57357509 by 561
The aim is to understand the frequency of 561 in 57357509.

Step 1:
561 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 561

Let's proceed to step 2:
561 goes into 57 0 times with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Append the next digit (3) from the dividend to 57 and continue with: 573 / 561

Moving on to step 3:
When dividing 573 by 561, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 12 after subtracting 561 from 573.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 561

Going ahead to step 4:
When dividing 125 by 561, we get 0 with a remainder of 125.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 125 to get 125.
Include the next digit (7) from the dividend after 125, then repeat: 1257 / 561

Advancing to step 5:
If we divide 1257 by 561, we get 2 and a remainder of 135.
Write down 2 as next digit of the result. 
Result so far: 102.0
The remainder is 135 after subtracting 1122 from 1257.
Bring next digit (5) of the dividend behind the 135 and repeat the process: 1355 / 561

Going ahead to step 6:
When dividing 1355 by 561, we get 2 with a remainder of 233.
The number 2 becomes the next digit in our result. 
Result so far: 1022.0
Subtract 1122 from 1355 to get 233.
Fetch the next digit (0) from the dividend, attach it to 233 and continue: 2330 / 561

Advancing to step 7:
561 can be fit into 2330 4 times, resulting in a remainder of 86.
Record the quotient 4 as the next digit in the result. 
Result so far: 10224.0
If we take 2244 away from 2330, we end up with 86.
Include the next digit (9) from the dividend after 86, then repeat: 869 / 561

Going ahead to step 8:
561 can be fit into 869 1 times, resulting in a remainder of 308.
Record the quotient 1 as the next digit in the result. 
Result so far: 102241.0
Deduct 561 from 869 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 9:
3080 divided by 561 is 5 with a remainder of 275.
The next digit of our result is 5. 
Result so far: 102241.5
Deduct 2805 from 3080 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 10:
561 can be fit into 2750 4 times, resulting in a remainder of 506.
Put 4 as the next digit of the answer. 
Result so far: 102241.54
If we subtract 2244 from 2750, we get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Going ahead to step 11:
When dividing 5060 by 561, we get 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 102241.549
Subtract 5049 from 5060 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 12:
110 divided by 561 is 0 with a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 102241.549
Subtracting 0 from 110 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 13:
The number 561 fits into 1100 1 times, leaving a remainder of 539.
Write down 1 as next digit of the result. 
Result so far: 102241.54901
Subtracting 561 from 1100 leaves us with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Let's proceed to step 14:
When dividing 5390 by 561, we get 9 with a remainder of 341.
The number 9 becomes the next digit in our result. 
Result so far: 102241.549019
Deduct 5049 from 5390 and we're left with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Moving on to step 15:
561 can be fit into 3410 6 times, resulting in a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 102241.5490196
If we take 3366 away from 3410, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 16:
561 goes into 440 0 times with a remainder of 440.
Put 0 as the next digit of the answer. 
Result so far: 102241.5490196
Subtracting 0 from 440 leaves us with 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 quotient of the division is 102241.5490196, and the remainder is 4.4e-07.
