64981054 ÷ 350 
The aim is to understand the frequency of 350 in 64981054.

Going ahead to step 1:
350 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 350

Moving on to step 2:
350 can be fit into 64 0 times, resulting in a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Bring next digit (9) of the dividend behind the 64 and repeat the process: 649 / 350

Step 3:
350 can be fit into 649 1 times, resulting in a remainder of 299.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 350 from 649 leaves us with 299.
Bring next digit (8) of the dividend behind the 299 and repeat the process: 2998 / 350

Going ahead to step 4:
The number 350 fits into 2998 8 times, leaving a remainder of 198.
The next digit of our result is 8. 
Result so far: 18.0
Subtract 2800 from 2998 to get 198.
Grab the next digit (1) from the dividend, add it to 198, then carry on: 1981 / 350

Moving on to step 5:
350 goes into 1981 5 times with a remainder of 231.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
Subtracting 1750 from 1981 leaves us with 231.
Include the next digit (0) from the dividend after 231, then repeat: 2310 / 350

Step 6:
The number 350 fits into 2310 6 times, leaving a remainder of 210.
Use 6 as the next digit of our solution. 
Result so far: 1856.0
Subtracting 2100 from 2310 leaves us with 210.
Include the next digit (5) from the dividend after 210, then repeat: 2105 / 350

Step 7:
2105 divided by 350 is 6 with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 18566.0
Deduct 2100 from 2105 and we're left with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 350

On to step 8:
350 goes into 54 0 times with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 185660.0
Deduct 0 from 54 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 9:
The number 350 fits into 540 1 times, leaving a remainder of 190.
Use 1 as the next digit of our solution. 
Result so far: 185660.1
Subtract 350 from 540 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 10:
When dividing 1900 by 350, we get 5 with a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 185660.15
If we subtract 1750 from 1900, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 11:
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: 185660.154
If we subtract 1400 from 1500, we get 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 12:
The number 350 fits into 1000 2 times, leaving a remainder of 300.
Record the quotient 2 as the next digit in the result. 
Result so far: 185660.1542
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.

On to step 13:
The number 350 fits into 3000 8 times, leaving a remainder of 200.
Record the quotient 8 as the next digit in the result. 
Result so far: 185660.15428
Deduct 2800 from 3000 and we're left 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.

Moving on to step 14:
If we divide 2000 by 350, we get 5 and a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 185660.154285
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.

On to step 15:
350 goes into 2500 7 times with a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 185660.1542857
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.

Going ahead to step 16:
350 goes into 500 1 times with a remainder of 150.
Write down 1 as next digit of the result. 
Result so far: 185660.15428571
If we take 350 away from 500, we end up 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.

The quotient of the division is 185660.15428571, and the remainder is 1.5e-07.
