52113911 ÷ 763 
The aim is to understand the frequency of 763 in 52113911.

Going ahead to step 1:
763 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 763

Let's proceed to step 2:
When dividing 52 by 763, we get 0 with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 763

Step 3:
763 goes into 521 0 times with a remainder of 521.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 521 to get 521.
Include the next digit (1) from the dividend after 521, then repeat: 5211 / 763

Moving on to step 4:
763 can be fit into 5211 6 times, resulting in a remainder of 633.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 4578 from 5211 and we're left with 633.
Grab the next digit (3) from the dividend, add it to 633, then carry on: 6333 / 763

Advancing to step 5:
When dividing 6333 by 763, we get 8 with a remainder of 229.
Use 8 as the next digit of our solution. 
Result so far: 68.0
The remainder is 229 after subtracting 6104 from 6333.
Bring next digit (9) of the dividend behind the 229 and repeat the process: 2299 / 763

Advancing to step 6:
The number 763 fits into 2299 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 683.0
If we subtract 2289 from 2299, we get 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 763

Advancing to step 7:
If we divide 101 by 763, we get 0 and a remainder of 101.
The number 0 becomes the next digit in our result. 
Result so far: 6830.0
Deduct 0 from 101 and we're left with 101.
Fetch the next digit (1) from the dividend, attach it to 101 and continue: 1011 / 763

On to step 8:
763 goes into 1011 1 times with a remainder of 248.
The number 1 becomes the next digit in our result. 
Result so far: 68301.0
Subtracting 763 from 1011 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 9:
When dividing 2480 by 763, we get 3 with a remainder of 191.
The number 3 becomes the next digit in our result. 
Result so far: 68301.3
Deduct 2289 from 2480 and we're left with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

On to step 10:
When dividing 1910 by 763, we get 2 with a remainder of 384.
The next digit of our result is 2. 
Result so far: 68301.32
Subtract 1526 from 1910 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 11:
The number 763 fits into 3840 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 68301.325
Subtract 3815 from 3840 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 12:
763 can be fit into 250 0 times, resulting in a remainder of 250.
The next digit of our result is 0. 
Result so far: 68301.325
If we take 0 away from 250, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 13:
When dividing 2500 by 763, we get 3 with a remainder of 211.
The next digit of our result is 3. 
Result so far: 68301.32503
Deduct 2289 from 2500 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Let's proceed to step 14:
If we divide 2110 by 763, we get 2 and a remainder of 584.
Record the quotient 2 as the next digit in the result. 
Result so far: 68301.325032
Subtract 1526 from 2110 to get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Step 15:
The number 763 fits into 5840 7 times, leaving a remainder of 499.
Use 7 as the next digit of our solution. 
Result so far: 68301.3250327
If we take 5341 away from 5840, we end up with 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Advancing to step 16:
4990 divided by 763 is 6 with a remainder of 412.
The number 6 becomes the next digit in our result. 
Result so far: 68301.32503276
Subtracting 4578 from 4990 leaves us with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

The final outcome is 68301.32503276, with a leftover of 4.12e-07.
