80388474 ÷ 231 
We want to divide 80388474 by 231.

Step 1:
231 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 231

Step 2:
231 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Fetch the next digit (3) from the dividend, attach it to 80 and continue: 803 / 231

Going ahead to step 3:
The number 231 fits into 803 3 times, leaving a remainder of 110.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 693 from 803 leaves us with 110.
Take the next digit (8) from the dividend and append it to 110, then repeat: 1108 / 231

Advancing to step 4:
The number 231 fits into 1108 4 times, leaving a remainder of 184.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Deduct 924 from 1108 and we're left with 184.
Append the next digit (8) from the dividend to 184 and continue with: 1848 / 231

Advancing to step 5:
If we divide 1848 by 231, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 348.0
If we subtract 1848 from 1848, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 231

Moving on to step 6:
If we divide 4 by 231, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 3480.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 231

Let's proceed to step 7:
231 can be fit into 47 0 times, resulting in a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 34800.0
Deduct 0 from 47 and we're left with 47.
Take the next digit (4) from the dividend and append it to 47, then repeat: 474 / 231

Let's proceed to step 8:
231 goes into 474 2 times with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 348002.0
The remainder is 12 after subtracting 462 from 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
231 goes into 120 0 times with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 348002.0
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 10:
If we divide 1200 by 231, we get 5 and a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 348002.05
Deduct 1155 from 1200 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 11:
231 can be fit into 450 1 times, resulting in a remainder of 219.
Record the quotient 1 as the next digit in the result. 
Result so far: 348002.051
If we take 231 away from 450, we end up with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

On to step 12:
When dividing 2190 by 231, we get 9 with a remainder of 111.
The number 9 becomes the next digit in our result. 
Result so far: 348002.0519
If we take 2079 away from 2190, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Going ahead to step 13:
1110 divided by 231 is 4 with a remainder of 186.
The number 4 becomes the next digit in our result. 
Result so far: 348002.05194
Deduct 924 from 1110 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 14:
231 can be fit into 1860 8 times, resulting in a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 348002.051948
If we subtract 1848 from 1860, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 15:
If we divide 120 by 231, we get 0 and a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 348002.051948
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 16:
231 can be fit into 1200 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 348002.05194805
Deduct 1155 from 1200 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 348002.05194805, with a leftover of 4.5e-08.
