Let's divide 42113431 by 389
Our goal is to divide 42113431 by 389.

Advancing to step 1:
If we divide 4 by 389, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 389

Moving on to step 2:
If we divide 42 by 389, we get 0 and a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 389

Advancing to step 3:
When dividing 421 by 389, we get 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 389 from 421 to get 32.
Bring next digit (1) of the dividend behind the 32 and repeat the process: 321 / 389

Advancing to step 4:
389 can be fit into 321 0 times, resulting in a remainder of 321.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 321 to get 321.
Fetch the next digit (3) from the dividend, attach it to 321 and continue: 3213 / 389

Moving on to step 5:
If we divide 3213 by 389, we get 8 and a remainder of 101.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
The remainder is 101 after subtracting 3112 from 3213.
Fetch the next digit (4) from the dividend, attach it to 101 and continue: 1014 / 389

Going ahead to step 6:
When dividing 1014 by 389, we get 2 with a remainder of 236.
The next digit of our result is 2. 
Result so far: 1082.0
Subtract 778 from 1014 to get 236.
Include the next digit (3) from the dividend after 236, then repeat: 2363 / 389

Advancing to step 7:
389 can be fit into 2363 6 times, resulting in a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 10826.0
If we subtract 2334 from 2363, we get 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 389

Step 8:
When dividing 291 by 389, we get 0 with a remainder of 291.
Put 0 as the next digit of the answer. 
Result so far: 108260.0
Deduct 0 from 291 and we're left with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Going ahead to step 9:
When dividing 2910 by 389, we get 7 with a remainder of 187.
Put 7 as the next digit of the answer. 
Result so far: 108260.7
If we take 2723 away from 2910, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Moving on to step 10:
If we divide 1870 by 389, we get 4 and a remainder of 314.
Use 4 as the next digit of our solution. 
Result so far: 108260.74
Subtracting 1556 from 1870 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Let's proceed to step 11:
389 can be fit into 3140 8 times, resulting in a remainder of 28.
The next digit of our result is 8. 
Result so far: 108260.748
Subtracting 3112 from 3140 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 12:
The number 389 fits into 280 0 times, leaving a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 108260.748
The remainder is 280 after subtracting 0 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 13:
389 goes into 2800 7 times with a remainder of 77.
The next digit of our result is 7. 
Result so far: 108260.74807
The remainder is 77 after subtracting 2723 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 14:
If we divide 770 by 389, we get 1 and a remainder of 381.
The next digit of our result is 1. 
Result so far: 108260.748071
Subtracting 389 from 770 leaves us with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Going ahead to step 15:
If we divide 3810 by 389, we get 9 and a remainder of 309.
Write down 9 as next digit of the result. 
Result so far: 108260.7480719
The remainder is 309 after subtracting 3501 from 3810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

On to step 16:
3090 divided by 389 is 7 with a remainder of 367.
The number 7 becomes the next digit in our result. 
Result so far: 108260.74807197
Subtract 2723 from 3090 to get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

After the division, we end up with 108260.74807197 and a remainder of 3.67e-07.
