55085555 ÷ 402 
Let's see how many times 402 fits into 55085555.

Moving on to step 1:
5 divided by 402 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 402

On to step 2:
55 divided by 402 is 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Grab the next digit (0) from the dividend, add it to 55, then carry on: 550 / 402

On to step 3:
When dividing 550 by 402, we get 1 with a remainder of 148.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 402 away from 550, we end up with 148.
Append the next digit (8) from the dividend to 148 and continue with: 1488 / 402

Let's proceed to step 4:
The number 402 fits into 1488 3 times, leaving a remainder of 282.
The next digit of our result is 3. 
Result so far: 13.0
If we take 1206 away from 1488, we end up with 282.
Include the next digit (5) from the dividend after 282, then repeat: 2825 / 402

Step 5:
2825 divided by 402 is 7 with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 137.0
Subtracting 2814 from 2825 leaves us with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 402

On to step 6:
When dividing 115 by 402, we get 0 with a remainder of 115.
Record the quotient 0 as the next digit in the result. 
Result so far: 1370.0
The remainder is 115 after subtracting 0 from 115.
Append the next digit (5) from the dividend to 115 and continue with: 1155 / 402

Going ahead to step 7:
1155 divided by 402 is 2 with a remainder of 351.
Use 2 as the next digit of our solution. 
Result so far: 13702.0
Deduct 804 from 1155 and we're left with 351.
Bring next digit (5) of the dividend behind the 351 and repeat the process: 3515 / 402

Step 8:
402 goes into 3515 8 times with a remainder of 299.
The number 8 becomes the next digit in our result. 
Result so far: 137028.0
If we take 3216 away from 3515, we end up with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Advancing to step 9:
2990 divided by 402 is 7 with a remainder of 176.
Record the quotient 7 as the next digit in the result. 
Result so far: 137028.7
Deduct 2814 from 2990 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 10:
The number 402 fits into 1760 4 times, leaving a remainder of 152.
Use 4 as the next digit of our solution. 
Result so far: 137028.74
If we take 1608 away from 1760, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 11:
The number 402 fits into 1520 3 times, leaving a remainder of 314.
The number 3 becomes the next digit in our result. 
Result so far: 137028.743
Subtracting 1206 from 1520 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Let's proceed to step 12:
If we divide 3140 by 402, we get 7 and a remainder of 326.
The number 7 becomes the next digit in our result. 
Result so far: 137028.7437
Subtract 2814 from 3140 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Going ahead to step 13:
When dividing 3260 by 402, we get 8 with a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 137028.74378
Deduct 3216 from 3260 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 14:
440 divided by 402 is 1 with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 137028.743781
Subtract 402 from 440 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 15:
When dividing 380 by 402, we get 0 with a remainder of 380.
Record the quotient 0 as the next digit in the result. 
Result so far: 137028.743781
Subtract 0 from 380 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 16:
402 goes into 3800 9 times with a remainder of 182.
The number 9 becomes the next digit in our result. 
Result so far: 137028.74378109
If we take 3618 away from 3800, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

After the division, we end up with 137028.74378109 and a remainder of 1.82e-07.
