97787904 ÷ 388 
We want to divide 97787904 by 388.

Advancing to step 1:
The number 388 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 388

Moving on to step 2:
The number 388 fits into 97 0 times, leaving a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 97 after subtracting 0 from 97.
Take the next digit (7) from the dividend and append it to 97, then repeat: 977 / 388

Advancing to step 3:
If we divide 977 by 388, we get 2 and a remainder of 201.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 201 after subtracting 776 from 977.
Grab the next digit (8) from the dividend, add it to 201, then carry on: 2018 / 388

Step 4:
If we divide 2018 by 388, we get 5 and a remainder of 78.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtracting 1940 from 2018 leaves us with 78.
Fetch the next digit (7) from the dividend, attach it to 78 and continue: 787 / 388

On to step 5:
The number 388 fits into 787 2 times, leaving a remainder of 11.
The next digit of our result is 2. 
Result so far: 252.0
If we take 776 away from 787, we end up with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 388

Moving on to step 6:
119 divided by 388 is 0 with a remainder of 119.
Record the quotient 0 as the next digit in the result. 
Result so far: 2520.0
If we subtract 0 from 119, we get 119.
Include the next digit (0) from the dividend after 119, then repeat: 1190 / 388

Advancing to step 7:
When dividing 1190 by 388, we get 3 with a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 25203.0
Subtract 1164 from 1190 to get 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 388

Step 8:
When dividing 264 by 388, we get 0 with a remainder of 264.
Write down 0 as next digit of the result. 
Result so far: 252030.0
Subtracting 0 from 264 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 9:
The number 388 fits into 2640 6 times, leaving a remainder of 312.
Record the quotient 6 as the next digit in the result. 
Result so far: 252030.6
Deduct 2328 from 2640 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 10:
3120 divided by 388 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 252030.68
If we subtract 3104 from 3120, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
The number 388 fits into 160 0 times, leaving a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 252030.68
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 12:
When dividing 1600 by 388, we get 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 252030.6804
Deduct 1552 from 1600 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 13:
When dividing 480 by 388, we get 1 with a remainder of 92.
Record the quotient 1 as the next digit in the result. 
Result so far: 252030.68041
Subtract 388 from 480 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 14:
920 divided by 388 is 2 with a remainder of 144.
The next digit of our result is 2. 
Result so far: 252030.680412
Subtracting 776 from 920 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 15:
When dividing 1440 by 388, we get 3 with a remainder of 276.
The number 3 becomes the next digit in our result. 
Result so far: 252030.6804123
The remainder is 276 after subtracting 1164 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 16:
388 goes into 2760 7 times with a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 252030.68041237
Subtracting 2716 from 2760 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.

The final outcome is 252030.68041237, with a leftover of 4.4e-08.
