We look at the division of 76640190 by 350 
The aim is to understand the frequency of 350 in 76640190.

On to step 1:
350 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 350

Step 2:
76 divided by 350 is 0 with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Append the next digit (6) from the dividend to 76 and continue with: 766 / 350

Let's proceed to step 3:
350 goes into 766 2 times with a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 700 from 766, we get 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 350

Moving on to step 4:
350 can be fit into 664 1 times, resulting in a remainder of 314.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 350 from 664, we get 314.
Fetch the next digit (0) from the dividend, attach it to 314 and continue: 3140 / 350

Moving on to step 5:
If we divide 3140 by 350, we get 8 and a remainder of 340.
The next digit of our result is 8. 
Result so far: 218.0
Deduct 2800 from 3140 and we're left with 340.
Take the next digit (1) from the dividend and append it to 340, then repeat: 3401 / 350

Step 6:
The number 350 fits into 3401 9 times, leaving a remainder of 251.
Put 9 as the next digit of the answer. 
Result so far: 2189.0
If we take 3150 away from 3401, we end up with 251.
Fetch the next digit (9) from the dividend, attach it to 251 and continue: 2519 / 350

On to step 7:
If we divide 2519 by 350, we get 7 and a remainder of 69.
The next digit of our result is 7. 
Result so far: 21897.0
If we subtract 2450 from 2519, we get 69.
Take the next digit (0) from the dividend and append it to 69, then repeat: 690 / 350

On to step 8:
690 divided by 350 is 1 with a remainder of 340.
The number 1 becomes the next digit in our result. 
Result so far: 218971.0
Subtracting 350 from 690 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.

Moving on to step 9:
3400 divided by 350 is 9 with a remainder of 250.
Use 9 as the next digit of our solution. 
Result so far: 218971.9
Subtracting 3150 from 3400 leaves us 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.

On to step 10:
The number 350 fits into 2500 7 times, leaving a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 218971.97
Subtracting 2450 from 2500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
The number 350 fits into 500 1 times, leaving a remainder of 150.
The next digit of our result is 1. 
Result so far: 218971.971
The remainder is 150 after subtracting 350 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 12:
350 goes into 1500 4 times with a remainder of 100.
The number 4 becomes the next digit in our result. 
Result so far: 218971.9714
The remainder is 100 after subtracting 1400 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 13:
350 can be fit into 1000 2 times, resulting in a remainder of 300.
Record the quotient 2 as the next digit in the result. 
Result so far: 218971.97142
Subtracting 700 from 1000 leaves us 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.

Going ahead to step 14:
When dividing 3000 by 350, we get 8 with a remainder of 200.
Write down 8 as next digit of the result. 
Result so far: 218971.971428
If we take 2800 away from 3000, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 15:
When dividing 2000 by 350, we get 5 with a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 218971.9714285
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.

Let's proceed to step 16:
350 goes into 2500 7 times with a remainder of 50.
Write down 7 as next digit of the result. 
Result so far: 218971.97142857
Subtracting 2450 from 2500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 218971.97142857 with a remaining 5e-08.
