79311487 ÷ 389 
Our goal is to divide 79311487 by 389.

Going ahead to step 1:
The number 389 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 389

Let's proceed to step 2:
If we divide 79 by 389, we get 0 and a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Take the next digit (3) from the dividend and append it to 79, then repeat: 793 / 389

Going ahead to step 3:
The number 389 fits into 793 2 times, leaving a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 778 from 793 to get 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 389

Advancing to step 4:
The number 389 fits into 151 0 times, leaving a remainder of 151.
Put 0 as the next digit of the answer. 
Result so far: 20.0
The remainder is 151 after subtracting 0 from 151.
Append the next digit (1) from the dividend to 151 and continue with: 1511 / 389

Moving on to step 5:
389 can be fit into 1511 3 times, resulting in a remainder of 344.
The number 3 becomes the next digit in our result. 
Result so far: 203.0
Subtract 1167 from 1511 to get 344.
Bring next digit (4) of the dividend behind the 344 and repeat the process: 3444 / 389

On to step 6:
When dividing 3444 by 389, we get 8 with a remainder of 332.
The next digit of our result is 8. 
Result so far: 2038.0
The remainder is 332 after subtracting 3112 from 3444.
Take the next digit (8) from the dividend and append it to 332, then repeat: 3328 / 389

Step 7:
389 can be fit into 3328 8 times, resulting in a remainder of 216.
The next digit of our result is 8. 
Result so far: 20388.0
The remainder is 216 after subtracting 3112 from 3328.
Append the next digit (7) from the dividend to 216 and continue with: 2167 / 389

On to step 8:
The number 389 fits into 2167 5 times, leaving a remainder of 222.
Write down 5 as next digit of the result. 
Result so far: 203885.0
If we subtract 1945 from 2167, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Let's proceed to step 9:
389 goes into 2220 5 times with a remainder of 275.
Record the quotient 5 as the next digit in the result. 
Result so far: 203885.5
If we take 1945 away from 2220, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 10:
389 can be fit into 2750 7 times, resulting in a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 203885.57
Subtracting 2723 from 2750 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 11:
270 divided by 389 is 0 with a remainder of 270.
The next digit of our result is 0. 
Result so far: 203885.57
Subtract 0 from 270 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 12:
If we divide 2700 by 389, we get 6 and a remainder of 366.
Write down 6 as next digit of the result. 
Result so far: 203885.5706
If we take 2334 away from 2700, we end up with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Let's proceed to step 13:
389 can be fit into 3660 9 times, resulting in a remainder of 159.
The number 9 becomes the next digit in our result. 
Result so far: 203885.57069
If we take 3501 away from 3660, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Step 14:
When dividing 1590 by 389, we get 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 203885.570694
Subtracting 1556 from 1590 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 15:
If we divide 340 by 389, we get 0 and a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 203885.570694
If we subtract 0 from 340, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 16:
If we divide 3400 by 389, we get 8 and a remainder of 288.
Record the quotient 8 as the next digit in the result. 
Result so far: 203885.57069408
The remainder is 288 after subtracting 3112 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final outcome is 203885.57069408, with a leftover of 2.88e-07.
