53007858 divided by 899 
We want to figure out the number of times 53007858 can be divided by 899.

Moving on to step 1:
899 goes into 5 0 times 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.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 899

Going ahead to step 2:
53 divided by 899 is 0 with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Append the next digit (0) from the dividend to 53 and continue with: 530 / 899

On to step 3:
If we divide 530 by 899, we get 0 and a remainder of 530.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 530, we end up with 530.
Append the next digit (0) from the dividend to 530 and continue with: 5300 / 899

Let's proceed to step 4:
If we divide 5300 by 899, we get 5 and a remainder of 805.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 4495 from 5300 to get 805.
Include the next digit (7) from the dividend after 805, then repeat: 8057 / 899

Step 5:
899 can be fit into 8057 8 times, resulting in a remainder of 865.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Subtract 7192 from 8057 to get 865.
Include the next digit (8) from the dividend after 865, then repeat: 8658 / 899

On to step 6:
When dividing 8658 by 899, we get 9 with a remainder of 567.
The number 9 becomes the next digit in our result. 
Result so far: 589.0
Deduct 8091 from 8658 and we're left with 567.
Append the next digit (5) from the dividend to 567 and continue with: 5675 / 899

Advancing to step 7:
The number 899 fits into 5675 6 times, leaving a remainder of 281.
Record the quotient 6 as the next digit in the result. 
Result so far: 5896.0
Subtract 5394 from 5675 to get 281.
Fetch the next digit (8) from the dividend, attach it to 281 and continue: 2818 / 899

Step 8:
If we divide 2818 by 899, we get 3 and a remainder of 121.
Write down 3 as next digit of the result. 
Result so far: 58963.0
Deduct 2697 from 2818 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 9:
The number 899 fits into 1210 1 times, leaving a remainder of 311.
Write down 1 as next digit of the result. 
Result so far: 58963.1
If we take 899 away from 1210, we end up with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Step 10:
The number 899 fits into 3110 3 times, leaving a remainder of 413.
Write down 3 as next digit of the result. 
Result so far: 58963.13
Deduct 2697 from 3110 and we're left with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Going ahead to step 11:
When dividing 4130 by 899, we get 4 with a remainder of 534.
The number 4 becomes the next digit in our result. 
Result so far: 58963.134
The remainder is 534 after subtracting 3596 from 4130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Advancing to step 12:
5340 divided by 899 is 5 with a remainder of 845.
The next digit of our result is 5. 
Result so far: 58963.1345
Subtract 4495 from 5340 to get 845.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8450, and continue the process.

Advancing to step 13:
When dividing 8450 by 899, we get 9 with a remainder of 359.
Put 9 as the next digit of the answer. 
Result so far: 58963.13459
Subtracting 8091 from 8450 leaves us with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

On to step 14:
The number 899 fits into 3590 3 times, leaving a remainder of 893.
Record the quotient 3 as the next digit in the result. 
Result so far: 58963.134593
Deduct 2697 from 3590 and we're left with 893.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8930, and continue the process.

On to step 15:
If we divide 8930 by 899, we get 9 and a remainder of 839.
Use 9 as the next digit of our solution. 
Result so far: 58963.1345939
Deduct 8091 from 8930 and we're left with 839.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8390, and continue the process.

Let's proceed to step 16:
The number 899 fits into 8390 9 times, leaving a remainder of 299.
Put 9 as the next digit of the answer. 
Result so far: 58963.13459399
Deduct 8091 from 8390 and we're left 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.

The quotient of the division is 58963.13459399, and the remainder is 2.99e-07.
