We look at the division of 55987591 by 510 
Let's see how many times 510 fits into 55987591.

Step 1:
5 divided by 510 is 0 with 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.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 510

Let's proceed to step 2:
If we divide 55 by 510, we get 0 and a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Append the next digit (9) from the dividend to 55 and continue with: 559 / 510

Moving on to step 3:
When dividing 559 by 510, we get 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 49 after subtracting 510 from 559.
Include the next digit (8) from the dividend after 49, then repeat: 498 / 510

Let's proceed to step 4:
If we divide 498 by 510, we get 0 and a remainder of 498.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 498 to get 498.
Include the next digit (7) from the dividend after 498, then repeat: 4987 / 510

On to step 5:
If we divide 4987 by 510, we get 9 and a remainder of 397.
The next digit of our result is 9. 
Result so far: 109.0
Subtracting 4590 from 4987 leaves us with 397.
Take the next digit (5) from the dividend and append it to 397, then repeat: 3975 / 510

Advancing to step 6:
If we divide 3975 by 510, we get 7 and a remainder of 405.
The next digit of our result is 7. 
Result so far: 1097.0
If we take 3570 away from 3975, we end up with 405.
Take the next digit (9) from the dividend and append it to 405, then repeat: 4059 / 510

Let's proceed to step 7:
510 can be fit into 4059 7 times, resulting in a remainder of 489.
Use 7 as the next digit of our solution. 
Result so far: 10977.0
If we subtract 3570 from 4059, we get 489.
Take the next digit (1) from the dividend and append it to 489, then repeat: 4891 / 510

Let's proceed to step 8:
If we divide 4891 by 510, we get 9 and a remainder of 301.
Write down 9 as next digit of the result. 
Result so far: 109779.0
If we subtract 4590 from 4891, we get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Let's proceed to step 9:
510 can be fit into 3010 5 times, resulting in a remainder of 460.
Put 5 as the next digit of the answer. 
Result so far: 109779.5
Subtracting 2550 from 3010 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 10:
4600 divided by 510 is 9 with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 109779.59
Deduct 4590 from 4600 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
The number 510 fits into 100 0 times, leaving a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 109779.59
If we take 0 away from 100, we end up 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.

Let's proceed to step 12:
1000 divided by 510 is 1 with a remainder of 490.
Write down 1 as next digit of the result. 
Result so far: 109779.5901
Subtract 510 from 1000 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 13:
510 can be fit into 4900 9 times, resulting in a remainder of 310.
Record the quotient 9 as the next digit in the result. 
Result so far: 109779.59019
Subtract 4590 from 4900 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 14:
When dividing 3100 by 510, we get 6 with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 109779.590196
Subtract 3060 from 3100 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 15:
When dividing 400 by 510, we get 0 with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 109779.590196
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 16:
510 can be fit into 4000 7 times, resulting in a remainder of 430.
Record the quotient 7 as the next digit in the result. 
Result so far: 109779.59019607
Deduct 3570 from 4000 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

The quotient of the division is 109779.59019607, and the remainder is 4.3e-07.
