55255931 ÷ 145 
Our goal is to divide 55255931 by 145.

Let's proceed to step 1:
5 divided by 145 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 145

Moving on to step 2:
145 goes into 55 0 times with a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Take the next digit (2) from the dividend and append it to 55, then repeat: 552 / 145

Step 3:
145 can be fit into 552 3 times, resulting in a remainder of 117.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 435 from 552 leaves us with 117.
Take the next digit (5) from the dividend and append it to 117, then repeat: 1175 / 145

Advancing to step 4:
If we divide 1175 by 145, we get 8 and a remainder of 15.
The next digit of our result is 8. 
Result so far: 38.0
Subtracting 1160 from 1175 leaves us with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 145

On to step 5:
145 can be fit into 155 1 times, resulting in a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 381.0
Deduct 145 from 155 and we're left with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 145

Let's proceed to step 6:
145 can be fit into 109 0 times, resulting in a remainder of 109.
The next digit of our result is 0. 
Result so far: 3810.0
Subtracting 0 from 109 leaves us with 109.
Include the next digit (3) from the dividend after 109, then repeat: 1093 / 145

Going ahead to step 7:
If we divide 1093 by 145, we get 7 and a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 38107.0
If we take 1015 away from 1093, we end up with 78.
Take the next digit (1) from the dividend and append it to 78, then repeat: 781 / 145

Let's proceed to step 8:
The number 145 fits into 781 5 times, leaving a remainder of 56.
Record the quotient 5 as the next digit in the result. 
Result so far: 381075.0
If we take 725 away from 781, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
560 divided by 145 is 3 with a remainder of 125.
The next digit of our result is 3. 
Result so far: 381075.3
Subtract 435 from 560 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 10:
If we divide 1250 by 145, we get 8 and a remainder of 90.
Put 8 as the next digit of the answer. 
Result so far: 381075.38
Subtracting 1160 from 1250 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 11:
145 goes into 900 6 times with a remainder of 30.
The next digit of our result is 6. 
Result so far: 381075.386
Subtract 870 from 900 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
145 goes into 300 2 times with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 381075.3862
Subtract 290 from 300 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
The number 145 fits into 100 0 times, leaving a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 381075.3862
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 14:
145 can be fit into 1000 6 times, resulting in a remainder of 130.
The next digit of our result is 6. 
Result so far: 381075.386206
If we take 870 away from 1000, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 15:
When dividing 1300 by 145, we get 8 with a remainder of 140.
The next digit of our result is 8. 
Result so far: 381075.3862068
Subtracting 1160 from 1300 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 16:
The number 145 fits into 1400 9 times, leaving a remainder of 95.
The number 9 becomes the next digit in our result. 
Result so far: 381075.38620689
Subtract 1305 from 1400 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

The final result is 381075.38620689 with a remainder of 9.5e-08.
