We're dividing 99401864 by 60 
We're looking to find how many times 60 goes into 99401864.

Step 1:
The number 60 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 60

On to step 2:
60 can be fit into 99 1 times, resulting in a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 60 from 99 and we're left with 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 60

Advancing to step 3:
The number 60 fits into 394 6 times, leaving a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 34 after subtracting 360 from 394.
Fetch the next digit (0) from the dividend, attach it to 34 and continue: 340 / 60

Advancing to step 4:
When dividing 340 by 60, we get 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 165.0
Subtract 300 from 340 to get 40.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 60

Let's proceed to step 5:
When dividing 401 by 60, we get 6 with a remainder of 41.
The next digit of our result is 6. 
Result so far: 1656.0
If we subtract 360 from 401, we get 41.
Bring next digit (8) of the dividend behind the 41 and repeat the process: 418 / 60

Going ahead to step 6:
60 can be fit into 418 6 times, resulting in a remainder of 58.
Write down 6 as next digit of the result. 
Result so far: 16566.0
The remainder is 58 after subtracting 360 from 418.
Fetch the next digit (6) from the dividend, attach it to 58 and continue: 586 / 60

Advancing to step 7:
60 goes into 586 9 times with a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 165669.0
Subtract 540 from 586 to get 46.
Bring next digit (4) of the dividend behind the 46 and repeat the process: 464 / 60

Going ahead to step 8:
The number 60 fits into 464 7 times, leaving a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 1656697.0
Subtracting 420 from 464 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
60 goes into 440 7 times with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 1656697.7
Subtracting 420 from 440 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.

Advancing to step 10:
60 can be fit into 200 3 times, resulting in a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 1656697.73
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
When dividing 200 by 60, we get 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 1656697.733
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 1656697.733 and a remainder of 0.002.
