We look at the division of 54386558 by 389 
We want to divide 54386558 by 389.

Step 1:
389 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 389

Moving on to step 2:
If we divide 54 by 389, we get 0 and a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 389

Advancing to step 3:
389 can be fit into 543 1 times, resulting in a remainder of 154.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 154 after subtracting 389 from 543.
Bring next digit (8) of the dividend behind the 154 and repeat the process: 1548 / 389

Advancing to step 4:
389 can be fit into 1548 3 times, resulting in a remainder of 381.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 1167 from 1548 to get 381.
Append the next digit (6) from the dividend to 381 and continue with: 3816 / 389

Step 5:
When dividing 3816 by 389, we get 9 with a remainder of 315.
Put 9 as the next digit of the answer. 
Result so far: 139.0
The remainder is 315 after subtracting 3501 from 3816.
Fetch the next digit (5) from the dividend, attach it to 315 and continue: 3155 / 389

Going ahead to step 6:
389 can be fit into 3155 8 times, resulting in a remainder of 43.
Write down 8 as next digit of the result. 
Result so far: 1398.0
The remainder is 43 after subtracting 3112 from 3155.
Grab the next digit (5) from the dividend, add it to 43, then carry on: 435 / 389

Let's proceed to step 7:
When dividing 435 by 389, we get 1 with a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 13981.0
Deduct 389 from 435 and we're left with 46.
Include the next digit (8) from the dividend after 46, then repeat: 468 / 389

Advancing to step 8:
468 divided by 389 is 1 with a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 139811.0
Subtract 389 from 468 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 9:
The number 389 fits into 790 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 139811.2
Deduct 778 from 790 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
389 goes into 120 0 times with a remainder of 120.
The next digit of our result is 0. 
Result so far: 139811.2
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 11:
1200 divided by 389 is 3 with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 139811.203
Deduct 1167 from 1200 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 12:
389 goes into 330 0 times with a remainder of 330.
Put 0 as the next digit of the answer. 
Result so far: 139811.203
The remainder is 330 after subtracting 0 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 13:
The number 389 fits into 3300 8 times, leaving a remainder of 188.
Record the quotient 8 as the next digit in the result. 
Result so far: 139811.20308
Subtract 3112 from 3300 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 14:
When dividing 1880 by 389, we get 4 with a remainder of 324.
Record the quotient 4 as the next digit in the result. 
Result so far: 139811.203084
If we subtract 1556 from 1880, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Going ahead to step 15:
3240 divided by 389 is 8 with a remainder of 128.
The number 8 becomes the next digit in our result. 
Result so far: 139811.2030848
The remainder is 128 after subtracting 3112 from 3240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 16:
The number 389 fits into 1280 3 times, leaving a remainder of 113.
The number 3 becomes the next digit in our result. 
Result so far: 139811.20308483
The remainder is 113 after subtracting 1167 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

After the division, we end up with 139811.20308483 and a remainder of 1.13e-07.
