Let's divide 77457716 by 351
The aim is to understand the frequency of 351 in 77457716.

Step 1:
351 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 351

Advancing to step 2:
77 divided by 351 is 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Fetch the next digit (4) from the dividend, attach it to 77 and continue: 774 / 351

Let's proceed to step 3:
351 goes into 774 2 times with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 702 from 774 to get 72.
Append the next digit (5) from the dividend to 72 and continue with: 725 / 351

Moving on to step 4:
The number 351 fits into 725 2 times, leaving a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtracting 702 from 725 leaves us with 23.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 351

On to step 5:
When dividing 237 by 351, we get 0 with a remainder of 237.
The number 0 becomes the next digit in our result. 
Result so far: 220.0
Deduct 0 from 237 and we're left with 237.
Bring next digit (7) of the dividend behind the 237 and repeat the process: 2377 / 351

Advancing to step 6:
The number 351 fits into 2377 6 times, leaving a remainder of 271.
Put 6 as the next digit of the answer. 
Result so far: 2206.0
Deduct 2106 from 2377 and we're left with 271.
Bring next digit (1) of the dividend behind the 271 and repeat the process: 2711 / 351

Moving on to step 7:
If we divide 2711 by 351, we get 7 and a remainder of 254.
Write down 7 as next digit of the result. 
Result so far: 22067.0
Deduct 2457 from 2711 and we're left with 254.
Grab the next digit (6) from the dividend, add it to 254, then carry on: 2546 / 351

Moving on to step 8:
351 can be fit into 2546 7 times, resulting in a remainder of 89.
Put 7 as the next digit of the answer. 
Result so far: 220677.0
Subtract 2457 from 2546 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 9:
890 divided by 351 is 2 with a remainder of 188.
Record the quotient 2 as the next digit in the result. 
Result so far: 220677.2
If we take 702 away from 890, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 10:
When dividing 1880 by 351, we get 5 with a remainder of 125.
The next digit of our result is 5. 
Result so far: 220677.25
If we subtract 1755 from 1880, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 11:
351 goes into 1250 3 times with a remainder of 197.
Write down 3 as next digit of the result. 
Result so far: 220677.253
If we take 1053 away from 1250, we end up with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Let's proceed to step 12:
351 can be fit into 1970 5 times, resulting in a remainder of 215.
Use 5 as the next digit of our solution. 
Result so far: 220677.2535
If we take 1755 away from 1970, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 13:
When dividing 2150 by 351, we get 6 with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 220677.25356
Subtract 2106 from 2150 to get 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 14:
351 can be fit into 440 1 times, resulting in a remainder of 89.
The number 1 becomes the next digit in our result. 
Result so far: 220677.253561
If we take 351 away from 440, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 15:
890 divided by 351 is 2 with a remainder of 188.
Record the quotient 2 as the next digit in the result. 
Result so far: 220677.2535612
The remainder is 188 after subtracting 702 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 16:
If we divide 1880 by 351, we get 5 and a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 220677.25356125
The remainder is 125 after subtracting 1755 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

The quotient of the division is 220677.25356125, and the remainder is 1.25e-07.
