We look at the division of 93974761 by 649 
The aim is to understand the frequency of 649 in 93974761.

Moving on to step 1:
649 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 649

On to step 2:
The number 649 fits into 93 0 times, leaving a remainder of 93.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 93 leaves us with 93.
Bring next digit (9) of the dividend behind the 93 and repeat the process: 939 / 649

On to step 3:
649 goes into 939 1 times with a remainder of 290.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 649 from 939 and we're left with 290.
Bring next digit (7) of the dividend behind the 290 and repeat the process: 2907 / 649

Moving on to step 4:
649 can be fit into 2907 4 times, resulting in a remainder of 311.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 2596 from 2907 leaves us with 311.
Bring next digit (4) of the dividend behind the 311 and repeat the process: 3114 / 649

Step 5:
3114 divided by 649 is 4 with a remainder of 518.
Use 4 as the next digit of our solution. 
Result so far: 144.0
Subtracting 2596 from 3114 leaves us with 518.
Grab the next digit (7) from the dividend, add it to 518, then carry on: 5187 / 649

Step 6:
If we divide 5187 by 649, we get 7 and a remainder of 644.
Write down 7 as next digit of the result. 
Result so far: 1447.0
If we subtract 4543 from 5187, we get 644.
Bring next digit (6) of the dividend behind the 644 and repeat the process: 6446 / 649

Let's proceed to step 7:
If we divide 6446 by 649, we get 9 and a remainder of 605.
Use 9 as the next digit of our solution. 
Result so far: 14479.0
The remainder is 605 after subtracting 5841 from 6446.
Fetch the next digit (1) from the dividend, attach it to 605 and continue: 6051 / 649

Going ahead to step 8:
649 goes into 6051 9 times with a remainder of 210.
Write down 9 as next digit of the result. 
Result so far: 144799.0
Deduct 5841 from 6051 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 9:
The number 649 fits into 2100 3 times, leaving a remainder of 153.
Write down 3 as next digit of the result. 
Result so far: 144799.3
If we take 1947 away from 2100, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 10:
If we divide 1530 by 649, we get 2 and a remainder of 232.
The next digit of our result is 2. 
Result so far: 144799.32
Deduct 1298 from 1530 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 11:
649 goes into 2320 3 times with a remainder of 373.
The number 3 becomes the next digit in our result. 
Result so far: 144799.323
Subtract 1947 from 2320 to get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

On to step 12:
649 can be fit into 3730 5 times, resulting in a remainder of 485.
Put 5 as the next digit of the answer. 
Result so far: 144799.3235
Subtract 3245 from 3730 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

On to step 13:
649 goes into 4850 7 times with a remainder of 307.
Record the quotient 7 as the next digit in the result. 
Result so far: 144799.32357
Subtract 4543 from 4850 to get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Step 14:
649 can be fit into 3070 4 times, resulting in a remainder of 474.
The next digit of our result is 4. 
Result so far: 144799.323574
Subtracting 2596 from 3070 leaves us with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Let's proceed to step 15:
If we divide 4740 by 649, we get 7 and a remainder of 197.
Put 7 as the next digit of the answer. 
Result so far: 144799.3235747
Subtracting 4543 from 4740 leaves us 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.

Step 16:
If we divide 1970 by 649, we get 3 and a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 144799.32357473
The remainder is 23 after subtracting 1947 from 1970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The quotient of the division is 144799.32357473, and the remainder is 2.3e-08.
