We look at the division of 52577640 by 350 
The aim is to understand the frequency of 350 in 52577640.

Advancing to step 1:
350 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 350

On to step 2:
350 can be fit into 52 0 times, resulting in a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Fetch the next digit (5) from the dividend, attach it to 52 and continue: 525 / 350

Advancing to step 3:
350 can be fit into 525 1 times, resulting in a remainder of 175.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 350 from 525 and we're left with 175.
Grab the next digit (7) from the dividend, add it to 175, then carry on: 1757 / 350

Advancing to step 4:
When dividing 1757 by 350, we get 5 with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 1750 from 1757 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 350

On to step 5:
The number 350 fits into 77 0 times, leaving a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
Subtracting 0 from 77 leaves us with 77.
Bring next digit (6) of the dividend behind the 77 and repeat the process: 776 / 350

Going ahead to step 6:
The number 350 fits into 776 2 times, leaving a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 1502.0
If we take 700 away from 776, we end up with 76.
Append the next digit (4) from the dividend to 76 and continue with: 764 / 350

Moving on to step 7:
If we divide 764 by 350, we get 2 and a remainder of 64.
The next digit of our result is 2. 
Result so far: 15022.0
If we take 700 away from 764, we end up with 64.
Append the next digit (0) from the dividend to 64 and continue with: 640 / 350

Step 8:
If we divide 640 by 350, we get 1 and a remainder of 290.
Write down 1 as next digit of the result. 
Result so far: 150221.0
The remainder is 290 after subtracting 350 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 9:
The number 350 fits into 2900 8 times, leaving a remainder of 100.
Record the quotient 8 as the next digit in the result. 
Result so far: 150221.8
Subtracting 2800 from 2900 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 10:
The number 350 fits into 1000 2 times, leaving a remainder of 300.
The number 2 becomes the next digit in our result. 
Result so far: 150221.82
Deduct 700 from 1000 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 11:
If we divide 3000 by 350, we get 8 and a remainder of 200.
Record the quotient 8 as the next digit in the result. 
Result so far: 150221.828
If we subtract 2800 from 3000, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 12:
350 goes into 2000 5 times with a remainder of 250.
The next digit of our result is 5. 
Result so far: 150221.8285
Deduct 1750 from 2000 and we're left 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.

Moving on to step 13:
When dividing 2500 by 350, we get 7 with a remainder of 50.
Write down 7 as next digit of the result. 
Result so far: 150221.82857
If we subtract 2450 from 2500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
350 goes into 500 1 times with a remainder of 150.
Record the quotient 1 as the next digit in the result. 
Result so far: 150221.828571
Deduct 350 from 500 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 15:
350 can be fit into 1500 4 times, resulting in a remainder of 100.
Put 4 as the next digit of the answer. 
Result so far: 150221.8285714
Deduct 1400 from 1500 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 16:
If we divide 1000 by 350, we get 2 and a remainder of 300.
Use 2 as the next digit of our solution. 
Result so far: 150221.82857142
If we subtract 700 from 1000, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The quotient of the division is 150221.82857142, and the remainder is 3e-07.
