Let's divide 31298099 by 388
We want to divide 31298099 by 388.

Let's proceed to step 1:
When dividing 3 by 388, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 388

Advancing to step 2:
388 can be fit into 31 0 times, resulting in a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 388

Let's proceed to step 3:
388 goes into 312 0 times with a remainder of 312.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 312 and we're left with 312.
Append the next digit (9) from the dividend to 312 and continue with: 3129 / 388

On to step 4:
388 can be fit into 3129 8 times, resulting in a remainder of 25.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 3104 from 3129 to get 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 388

On to step 5:
258 divided by 388 is 0 with a remainder of 258.
The next digit of our result is 0. 
Result so far: 80.0
If we subtract 0 from 258, we get 258.
Take the next digit (0) from the dividend and append it to 258, then repeat: 2580 / 388

Advancing to step 6:
2580 divided by 388 is 6 with a remainder of 252.
Write down 6 as next digit of the result. 
Result so far: 806.0
Deduct 2328 from 2580 and we're left with 252.
Grab the next digit (9) from the dividend, add it to 252, then carry on: 2529 / 388

Advancing to step 7:
2529 divided by 388 is 6 with a remainder of 201.
The number 6 becomes the next digit in our result. 
Result so far: 8066.0
If we subtract 2328 from 2529, we get 201.
Grab the next digit (9) from the dividend, add it to 201, then carry on: 2019 / 388

Let's proceed to step 8:
388 can be fit into 2019 5 times, resulting in a remainder of 79.
The number 5 becomes the next digit in our result. 
Result so far: 80665.0
The remainder is 79 after subtracting 1940 from 2019.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 9:
388 can be fit into 790 2 times, resulting in a remainder of 14.
The next digit of our result is 2. 
Result so far: 80665.2
Subtract 776 from 790 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
388 goes into 140 0 times with a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 80665.2
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 11:
If we divide 1400 by 388, we get 3 and a remainder of 236.
Use 3 as the next digit of our solution. 
Result so far: 80665.203
Deduct 1164 from 1400 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 12:
The number 388 fits into 2360 6 times, leaving a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 80665.2036
Deduct 2328 from 2360 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
When dividing 320 by 388, we get 0 with a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 80665.2036
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 14:
388 can be fit into 3200 8 times, resulting in a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 80665.203608
Subtract 3104 from 3200 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 15:
960 divided by 388 is 2 with a remainder of 184.
The number 2 becomes the next digit in our result. 
Result so far: 80665.2036082
Deduct 776 from 960 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 16:
The number 388 fits into 1840 4 times, leaving a remainder of 288.
The next digit of our result is 4. 
Result so far: 80665.20360824
If we subtract 1552 from 1840, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

In conclusion, the division gives 80665.20360824 with a balance of 2.88e-07.
