97717891 divided by 153 
The aim is to understand the frequency of 153 in 97717891.

Advancing to step 1:
The number 153 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 153

Step 2:
The number 153 fits into 97 0 times, leaving a remainder of 97.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 97, we end up with 97.
Take the next digit (7) from the dividend and append it to 97, then repeat: 977 / 153

Step 3:
153 can be fit into 977 6 times, resulting in a remainder of 59.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 918 from 977 leaves us with 59.
Append the next digit (1) from the dividend to 59 and continue with: 591 / 153

Let's proceed to step 4:
153 goes into 591 3 times with a remainder of 132.
The next digit of our result is 3. 
Result so far: 63.0
If we subtract 459 from 591, we get 132.
Bring next digit (7) of the dividend behind the 132 and repeat the process: 1327 / 153

Let's proceed to step 5:
The number 153 fits into 1327 8 times, leaving a remainder of 103.
Write down 8 as next digit of the result. 
Result so far: 638.0
Deduct 1224 from 1327 and we're left with 103.
Fetch the next digit (8) from the dividend, attach it to 103 and continue: 1038 / 153

Step 6:
The number 153 fits into 1038 6 times, leaving a remainder of 120.
The number 6 becomes the next digit in our result. 
Result so far: 6386.0
The remainder is 120 after subtracting 918 from 1038.
Grab the next digit (9) from the dividend, add it to 120, then carry on: 1209 / 153

Going ahead to step 7:
153 can be fit into 1209 7 times, resulting in a remainder of 138.
The number 7 becomes the next digit in our result. 
Result so far: 63867.0
If we subtract 1071 from 1209, we get 138.
Bring next digit (1) of the dividend behind the 138 and repeat the process: 1381 / 153

Going ahead to step 8:
153 can be fit into 1381 9 times, resulting in a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 638679.0
Deduct 1377 from 1381 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
40 divided by 153 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 638679.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
If we divide 400 by 153, we get 2 and a remainder of 94.
The next digit of our result is 2. 
Result so far: 638679.02
Deduct 306 from 400 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 11:
When dividing 940 by 153, we get 6 with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 638679.026
Deduct 918 from 940 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
When dividing 220 by 153, we get 1 with a remainder of 67.
Use 1 as the next digit of our solution. 
Result so far: 638679.0261
If we subtract 153 from 220, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 13:
If we divide 670 by 153, we get 4 and a remainder of 58.
The next digit of our result is 4. 
Result so far: 638679.02614
Deduct 612 from 670 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 14:
153 goes into 580 3 times with a remainder of 121.
Record the quotient 3 as the next digit in the result. 
Result so far: 638679.026143
Deduct 459 from 580 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Let's proceed to step 15:
If we divide 1210 by 153, we get 7 and a remainder of 139.
Write down 7 as next digit of the result. 
Result so far: 638679.0261437
If we subtract 1071 from 1210, we get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Step 16:
153 goes into 1390 9 times with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 638679.02614379
If we take 1377 away from 1390, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The quotient of the division is 638679.02614379, and the remainder is 1.3e-08.
