98973664 ÷ 388 
We're looking to find how many times 388 goes into 98973664.

Advancing to step 1:
If we divide 9 by 388, we get 0 and 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 (8) from the dividend after 9, then repeat: 98 / 388

Advancing to step 2:
388 goes into 98 0 times with a remainder of 98.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Bring next digit (9) of the dividend behind the 98 and repeat the process: 989 / 388

On to step 3:
388 goes into 989 2 times with a remainder of 213.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 776 from 989 and we're left with 213.
Fetch the next digit (7) from the dividend, attach it to 213 and continue: 2137 / 388

On to step 4:
2137 divided by 388 is 5 with a remainder of 197.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtracting 1940 from 2137 leaves us with 197.
Include the next digit (3) from the dividend after 197, then repeat: 1973 / 388

Moving on to step 5:
1973 divided by 388 is 5 with a remainder of 33.
The number 5 becomes the next digit in our result. 
Result so far: 255.0
Subtract 1940 from 1973 to get 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 388

Moving on to step 6:
388 can be fit into 336 0 times, resulting in a remainder of 336.
Put 0 as the next digit of the answer. 
Result so far: 2550.0
If we take 0 away from 336, we end up with 336.
Take the next digit (6) from the dividend and append it to 336, then repeat: 3366 / 388

On to step 7:
3366 divided by 388 is 8 with a remainder of 262.
Record the quotient 8 as the next digit in the result. 
Result so far: 25508.0
Subtracting 3104 from 3366 leaves us with 262.
Include the next digit (4) from the dividend after 262, then repeat: 2624 / 388

Step 8:
If we divide 2624 by 388, we get 6 and a remainder of 296.
Record the quotient 6 as the next digit in the result. 
Result so far: 255086.0
If we take 2328 away from 2624, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 9:
When dividing 2960 by 388, we get 7 with a remainder of 244.
The next digit of our result is 7. 
Result so far: 255086.7
Subtract 2716 from 2960 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 10:
When dividing 2440 by 388, we get 6 with a remainder of 112.
The next digit of our result is 6. 
Result so far: 255086.76
Subtracting 2328 from 2440 leaves us 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.

Moving on to step 11:
If we divide 1120 by 388, we get 2 and a remainder of 344.
The number 2 becomes the next digit in our result. 
Result so far: 255086.762
Subtract 776 from 1120 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

On to step 12:
388 can be fit into 3440 8 times, resulting in a remainder of 336.
The next digit of our result is 8. 
Result so far: 255086.7628
Subtracting 3104 from 3440 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 13:
388 goes into 3360 8 times with a remainder of 256.
Write down 8 as next digit of the result. 
Result so far: 255086.76288
Subtracting 3104 from 3360 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final outcome is 255086.76288, with a leftover of 0.000256.
