We divide 51115039 by 669
The aim is to understand the frequency of 669 in 51115039.

Going ahead to step 1:
669 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 669

Step 2:
When dividing 51 by 669, we get 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Append the next digit (1) from the dividend to 51 and continue with: 511 / 669

Step 3:
If we divide 511 by 669, we get 0 and a remainder of 511.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 511 after subtracting 0 from 511.
Grab the next digit (1) from the dividend, add it to 511, then carry on: 5111 / 669

Moving on to step 4:
669 can be fit into 5111 7 times, resulting in a remainder of 428.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 4683 from 5111 leaves us with 428.
Take the next digit (5) from the dividend and append it to 428, then repeat: 4285 / 669

Advancing to step 5:
669 goes into 4285 6 times with a remainder of 271.
Put 6 as the next digit of the answer. 
Result so far: 76.0
The remainder is 271 after subtracting 4014 from 4285.
Grab the next digit (0) from the dividend, add it to 271, then carry on: 2710 / 669

Step 6:
When dividing 2710 by 669, we get 4 with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 764.0
Deduct 2676 from 2710 and we're left with 34.
Grab the next digit (3) from the dividend, add it to 34, then carry on: 343 / 669

Moving on to step 7:
The number 669 fits into 343 0 times, leaving a remainder of 343.
Put 0 as the next digit of the answer. 
Result so far: 7640.0
Subtract 0 from 343 to get 343.
Bring next digit (9) of the dividend behind the 343 and repeat the process: 3439 / 669

Step 8:
The number 669 fits into 3439 5 times, leaving a remainder of 94.
Record the quotient 5 as the next digit in the result. 
Result so far: 76405.0
Subtract 3345 from 3439 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 9:
When dividing 940 by 669, we get 1 with a remainder of 271.
The number 1 becomes the next digit in our result. 
Result so far: 76405.1
Deduct 669 from 940 and we're left with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Moving on to step 10:
669 goes into 2710 4 times with a remainder of 34.
The next digit of our result is 4. 
Result so far: 76405.14
Deduct 2676 from 2710 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 11:
340 divided by 669 is 0 with a remainder of 340.
The next digit of our result is 0. 
Result so far: 76405.14
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 12:
669 can be fit into 3400 5 times, resulting in a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 76405.1405
If we take 3345 away from 3400, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 13:
If we divide 550 by 669, we get 0 and a remainder of 550.
The next digit of our result is 0. 
Result so far: 76405.1405
Deduct 0 from 550 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 14:
When dividing 5500 by 669, we get 8 with a remainder of 148.
The number 8 becomes the next digit in our result. 
Result so far: 76405.140508
Subtract 5352 from 5500 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 15:
If we divide 1480 by 669, we get 2 and a remainder of 142.
Use 2 as the next digit of our solution. 
Result so far: 76405.1405082
Subtracting 1338 from 1480 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 16:
1420 divided by 669 is 2 with a remainder of 82.
The next digit of our result is 2. 
Result so far: 76405.14050822
If we take 1338 away from 1420, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Our division results in 76405.14050822 with a remaining 8.2e-08.
