87697991 ÷ 60 
We want to figure out the number of times 87697991 can be divided by 60.

Moving on to step 1:
60 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 60

Going ahead to step 2:
60 goes into 87 1 times with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 60 from 87 to get 27.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 60

Moving on to step 3:
60 can be fit into 276 4 times, resulting in a remainder of 36.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 240 from 276 to get 36.
Include the next digit (9) from the dividend after 36, then repeat: 369 / 60

Going ahead to step 4:
60 can be fit into 369 6 times, resulting in a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 146.0
The remainder is 9 after subtracting 360 from 369.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 60

Step 5:
97 divided by 60 is 1 with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 1461.0
Deduct 60 from 97 and we're left with 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 60

Going ahead to step 6:
379 divided by 60 is 6 with a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 14616.0
Subtracting 360 from 379 leaves us with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 60

Step 7:
The number 60 fits into 199 3 times, leaving a remainder of 19.
The next digit of our result is 3. 
Result so far: 146163.0
The remainder is 19 after subtracting 180 from 199.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 60

Moving on to step 8:
If we divide 191 by 60, we get 3 and a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 1461633.0
The remainder is 11 after subtracting 180 from 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
The number 60 fits into 110 1 times, leaving a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 1461633.1
Subtracting 60 from 110 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.

On to step 10:
When dividing 500 by 60, we get 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 1461633.18
Deduct 480 from 500 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
60 goes into 200 3 times with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 1461633.183
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
60 goes into 200 3 times with a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 1461633.1833
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 1461633.1833 with a remainder of 0.0002.
