We're dividing 55388401 by 320 
Our goal is to divide 55388401 by 320.

Let's proceed to step 1:
5 divided by 320 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 320

On to step 2:
320 can be fit into 55 0 times, resulting in a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Bring next digit (3) of the dividend behind the 55 and repeat the process: 553 / 320

Moving on to step 3:
553 divided by 320 is 1 with a remainder of 233.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 320 from 553 to get 233.
Append the next digit (8) from the dividend to 233 and continue with: 2338 / 320

Going ahead to step 4:
320 can be fit into 2338 7 times, resulting in a remainder of 98.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 2240 from 2338, we get 98.
Append the next digit (8) from the dividend to 98 and continue with: 988 / 320

Step 5:
If we divide 988 by 320, we get 3 and a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 173.0
Deduct 960 from 988 and we're left with 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 320

Advancing to step 6:
320 goes into 284 0 times with a remainder of 284.
Use 0 as the next digit of our solution. 
Result so far: 1730.0
If we take 0 away from 284, we end up with 284.
Bring next digit (0) of the dividend behind the 284 and repeat the process: 2840 / 320

Step 7:
When dividing 2840 by 320, we get 8 with a remainder of 280.
Put 8 as the next digit of the answer. 
Result so far: 17308.0
Deduct 2560 from 2840 and we're left with 280.
Grab the next digit (1) from the dividend, add it to 280, then carry on: 2801 / 320

On to step 8:
320 can be fit into 2801 8 times, resulting in a remainder of 241.
The next digit of our result is 8. 
Result so far: 173088.0
Subtracting 2560 from 2801 leaves us with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Going ahead to step 9:
2410 divided by 320 is 7 with a remainder of 170.
Record the quotient 7 as the next digit in the result. 
Result so far: 173088.7
Deduct 2240 from 2410 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 10:
If we divide 1700 by 320, we get 5 and a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 173088.75
If we subtract 1600 from 1700, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 11:
When dividing 1000 by 320, we get 3 with a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 173088.753
If we take 960 away from 1000, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
If we divide 400 by 320, we get 1 and a remainder of 80.
Use 1 as the next digit of our solution. 
Result so far: 173088.7531
If we subtract 320 from 400, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
If we divide 800 by 320, we get 2 and a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 173088.75312
Deduct 640 from 800 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
The number 320 fits into 1600 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 173088.753125
If we take 1600 away from 1600, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 15:
If we divide 0 by 320, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 173088.753125
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 16:
The number 320 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 173088.753125
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 173088.753125 with a remainder of 0.0.
