55321901 ÷ 311 
We want to figure out the number of times 55321901 can be divided by 311.

Step 1:
If we divide 5 by 311, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 311

Going ahead to step 2:
When dividing 55 by 311, we get 0 with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Take the next digit (3) from the dividend and append it to 55, then repeat: 553 / 311

On to step 3:
If we divide 553 by 311, we get 1 and a remainder of 242.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 311 from 553 and we're left with 242.
Fetch the next digit (2) from the dividend, attach it to 242 and continue: 2422 / 311

Step 4:
The number 311 fits into 2422 7 times, leaving a remainder of 245.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 2177 from 2422 and we're left with 245.
Fetch the next digit (1) from the dividend, attach it to 245 and continue: 2451 / 311

Going ahead to step 5:
If we divide 2451 by 311, we get 7 and a remainder of 274.
Use 7 as the next digit of our solution. 
Result so far: 177.0
Subtracting 2177 from 2451 leaves us with 274.
Append the next digit (9) from the dividend to 274 and continue with: 2749 / 311

On to step 6:
311 can be fit into 2749 8 times, resulting in a remainder of 261.
Write down 8 as next digit of the result. 
Result so far: 1778.0
If we take 2488 away from 2749, we end up with 261.
Append the next digit (0) from the dividend to 261 and continue with: 2610 / 311

Let's proceed to step 7:
311 can be fit into 2610 8 times, resulting in a remainder of 122.
The number 8 becomes the next digit in our result. 
Result so far: 17788.0
Subtracting 2488 from 2610 leaves us with 122.
Take the next digit (1) from the dividend and append it to 122, then repeat: 1221 / 311

Advancing to step 8:
The number 311 fits into 1221 3 times, leaving a remainder of 288.
Put 3 as the next digit of the answer. 
Result so far: 177883.0
Deduct 933 from 1221 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 9:
2880 divided by 311 is 9 with a remainder of 81.
Record the quotient 9 as the next digit in the result. 
Result so far: 177883.9
The remainder is 81 after subtracting 2799 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 10:
The number 311 fits into 810 2 times, leaving a remainder of 188.
Put 2 as the next digit of the answer. 
Result so far: 177883.92
Subtracting 622 from 810 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 11:
1880 divided by 311 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 177883.926
The remainder is 14 after subtracting 1866 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
If we divide 140 by 311, we get 0 and a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 177883.926
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 13:
When dividing 1400 by 311, we get 4 with a remainder of 156.
Record the quotient 4 as the next digit in the result. 
Result so far: 177883.92604
Subtracting 1244 from 1400 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 14:
311 goes into 1560 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 177883.926045
If we take 1555 away from 1560, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 15:
When dividing 50 by 311, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 177883.926045
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 16:
311 goes into 500 1 times with a remainder of 189.
Use 1 as the next digit of our solution. 
Result so far: 177883.92604501
Deduct 311 from 500 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.

In conclusion, the division gives 177883.92604501 with a balance of 1.89e-07.
