97909616 ÷ 154 
We want to figure out the number of times 97909616 can be divided by 154.

On to step 1:
The number 154 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.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 154

On to step 2:
97 divided by 154 is 0 with a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 97 and we're left with 97.
Bring next digit (9) of the dividend behind the 97 and repeat the process: 979 / 154

Step 3:
154 can be fit into 979 6 times, resulting in a remainder of 55.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 924 from 979, we get 55.
Include the next digit (0) from the dividend after 55, then repeat: 550 / 154

Let's proceed to step 4:
550 divided by 154 is 3 with a remainder of 88.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Deduct 462 from 550 and we're left with 88.
Grab the next digit (9) from the dividend, add it to 88, then carry on: 889 / 154

Step 5:
If we divide 889 by 154, we get 5 and a remainder of 119.
The number 5 becomes the next digit in our result. 
Result so far: 635.0
The remainder is 119 after subtracting 770 from 889.
Bring next digit (6) of the dividend behind the 119 and repeat the process: 1196 / 154

Step 6:
When dividing 1196 by 154, we get 7 with a remainder of 118.
Record the quotient 7 as the next digit in the result. 
Result so far: 6357.0
If we take 1078 away from 1196, we end up with 118.
Bring next digit (1) of the dividend behind the 118 and repeat the process: 1181 / 154

Going ahead to step 7:
The number 154 fits into 1181 7 times, leaving a remainder of 103.
Write down 7 as next digit of the result. 
Result so far: 63577.0
Subtracting 1078 from 1181 leaves us with 103.
Bring next digit (6) of the dividend behind the 103 and repeat the process: 1036 / 154

On to step 8:
154 can be fit into 1036 6 times, resulting in a remainder of 112.
The next digit of our result is 6. 
Result so far: 635776.0
Deduct 924 from 1036 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 9:
154 goes into 1120 7 times with a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 635776.7
Deduct 1078 from 1120 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
If we divide 420 by 154, we get 2 and a remainder of 112.
The next digit of our result is 2. 
Result so far: 635776.72
If we take 308 away from 420, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 11:
When dividing 1120 by 154, we get 7 with a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 635776.727
Deduct 1078 from 1120 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 12:
154 can be fit into 420 2 times, resulting in a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 635776.7272
Subtract 308 from 420 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 13:
When dividing 1120 by 154, we get 7 with a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 635776.72727
Subtract 1078 from 1120 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 14:
420 divided by 154 is 2 with a remainder of 112.
Write down 2 as next digit of the result. 
Result so far: 635776.727272
If we subtract 308 from 420, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 15:
1120 divided by 154 is 7 with a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 635776.7272727
The remainder is 42 after subtracting 1078 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 16:
154 can be fit into 420 2 times, resulting in a remainder of 112.
The next digit of our result is 2. 
Result so far: 635776.72727272
If we subtract 308 from 420, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

After the division, we end up with 635776.72727272 and a remainder of 1.12e-07.
