55398457 ÷ 389 
We want to figure out the number of times 55398457 can be divided by 389.

Let's proceed to step 1:
If we divide 5 by 389, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 389

Advancing to step 2:
If we divide 55 by 389, we get 0 and a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Grab the next digit (3) from the dividend, add it to 55, then carry on: 553 / 389

Moving on to step 3:
When dividing 553 by 389, we get 1 with a remainder of 164.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 389 from 553 and we're left with 164.
Grab the next digit (9) from the dividend, add it to 164, then carry on: 1649 / 389

Moving on to step 4:
When dividing 1649 by 389, we get 4 with a remainder of 93.
The next digit of our result is 4. 
Result so far: 14.0
If we take 1556 away from 1649, we end up with 93.
Include the next digit (8) from the dividend after 93, then repeat: 938 / 389

Let's proceed to step 5:
389 can be fit into 938 2 times, resulting in a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 142.0
Subtracting 778 from 938 leaves us with 160.
Grab the next digit (4) from the dividend, add it to 160, then carry on: 1604 / 389

Step 6:
389 can be fit into 1604 4 times, resulting in a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 1424.0
Subtracting 1556 from 1604 leaves us with 48.
Include the next digit (5) from the dividend after 48, then repeat: 485 / 389

Step 7:
389 can be fit into 485 1 times, resulting in a remainder of 96.
Record the quotient 1 as the next digit in the result. 
Result so far: 14241.0
The remainder is 96 after subtracting 389 from 485.
Bring next digit (7) of the dividend behind the 96 and repeat the process: 967 / 389

Let's proceed to step 8:
If we divide 967 by 389, we get 2 and a remainder of 189.
The number 2 becomes the next digit in our result. 
Result so far: 142412.0
Deduct 778 from 967 and we're left with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Advancing to step 9:
389 can be fit into 1890 4 times, resulting in a remainder of 334.
The next digit of our result is 4. 
Result so far: 142412.4
Subtracting 1556 from 1890 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 10:
The number 389 fits into 3340 8 times, leaving a remainder of 228.
The next digit of our result is 8. 
Result so far: 142412.48
Deduct 3112 from 3340 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 11:
When dividing 2280 by 389, we get 5 with a remainder of 335.
The number 5 becomes the next digit in our result. 
Result so far: 142412.485
Deduct 1945 from 2280 and we're left with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

On to step 12:
If we divide 3350 by 389, we get 8 and a remainder of 238.
Use 8 as the next digit of our solution. 
Result so far: 142412.4858
If we subtract 3112 from 3350, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 13:
389 goes into 2380 6 times with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 142412.48586
Subtracting 2334 from 2380 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 14:
389 can be fit into 460 1 times, resulting in a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 142412.485861
The remainder is 71 after subtracting 389 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 15:
710 divided by 389 is 1 with a remainder of 321.
Write down 1 as next digit of the result. 
Result so far: 142412.4858611
Subtract 389 from 710 to get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

In conclusion, the division gives 142412.4858611 with a balance of 3.21e-06.
