We look at the division of 7389989 by 389 
We want to figure out the number of times 7389989 can be divided by 389.

Advancing to step 1:
389 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 389

Step 2:
When dividing 73 by 389, we get 0 with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Fetch the next digit (8) from the dividend, attach it to 73 and continue: 738 / 389

Going ahead to step 3:
If we divide 738 by 389, we get 1 and a remainder of 349.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 389 from 738 to get 349.
Include the next digit (9) from the dividend after 349, then repeat: 3499 / 389

Advancing to step 4:
If we divide 3499 by 389, we get 8 and a remainder of 387.
Use 8 as the next digit of our solution. 
Result so far: 18.0
The remainder is 387 after subtracting 3112 from 3499.
Fetch the next digit (9) from the dividend, attach it to 387 and continue: 3879 / 389

Advancing to step 5:
The number 389 fits into 3879 9 times, leaving a remainder of 378.
Record the quotient 9 as the next digit in the result. 
Result so far: 189.0
Subtracting 3501 from 3879 leaves us with 378.
Include the next digit (8) from the dividend after 378, then repeat: 3788 / 389

Step 6:
389 goes into 3788 9 times with a remainder of 287.
The next digit of our result is 9. 
Result so far: 1899.0
If we take 3501 away from 3788, we end up with 287.
Grab the next digit (9) from the dividend, add it to 287, then carry on: 2879 / 389

On to step 7:
When dividing 2879 by 389, we get 7 with a remainder of 156.
Record the quotient 7 as the next digit in the result. 
Result so far: 18997.0
If we take 2723 away from 2879, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 8:
The number 389 fits into 1560 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 18997.4
If we subtract 1556 from 1560, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
When dividing 40 by 389, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 18997.4
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
389 goes into 400 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 18997.401
Subtracting 389 from 400 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
389 goes into 110 0 times with a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 18997.401
The remainder is 110 after subtracting 0 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 12:
389 can be fit into 1100 2 times, resulting in a remainder of 322.
Put 2 as the next digit of the answer. 
Result so far: 18997.40102
Subtract 778 from 1100 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 13:
When dividing 3220 by 389, we get 8 with a remainder of 108.
Write down 8 as next digit of the result. 
Result so far: 18997.401028
Deduct 3112 from 3220 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 14:
389 goes into 1080 2 times with a remainder of 302.
The number 2 becomes the next digit in our result. 
Result so far: 18997.4010282
Subtract 778 from 1080 to get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Going ahead to step 15:
The number 389 fits into 3020 7 times, leaving a remainder of 297.
The next digit of our result is 7. 
Result so far: 18997.40102827
The remainder is 297 after subtracting 2723 from 3020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

The quotient of the division is 18997.40102827, and the remainder is 2.97e-07.
