We're dividing 53150671 by 803 
We're looking to find how many times 803 goes into 53150671.

Let's proceed to step 1:
5 divided by 803 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 803

Advancing to step 2:
When dividing 53 by 803, we get 0 with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Append the next digit (1) from the dividend to 53 and continue with: 531 / 803

Advancing to step 3:
If we divide 531 by 803, we get 0 and a remainder of 531.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 531 to get 531.
Bring next digit (5) of the dividend behind the 531 and repeat the process: 5315 / 803

Let's proceed to step 4:
5315 divided by 803 is 6 with a remainder of 497.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 4818 from 5315 and we're left with 497.
Take the next digit (0) from the dividend and append it to 497, then repeat: 4970 / 803

On to step 5:
4970 divided by 803 is 6 with a remainder of 152.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
Deduct 4818 from 4970 and we're left with 152.
Fetch the next digit (6) from the dividend, attach it to 152 and continue: 1526 / 803

Moving on to step 6:
The number 803 fits into 1526 1 times, leaving a remainder of 723.
Write down 1 as next digit of the result. 
Result so far: 661.0
Subtract 803 from 1526 to get 723.
Append the next digit (7) from the dividend to 723 and continue with: 7237 / 803

Advancing to step 7:
803 can be fit into 7237 9 times, resulting in a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 6619.0
Subtracting 7227 from 7237 leaves us with 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 803

Let's proceed to step 8:
803 can be fit into 101 0 times, resulting in a remainder of 101.
Write down 0 as next digit of the result. 
Result so far: 66190.0
Subtract 0 from 101 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 9:
When dividing 1010 by 803, we get 1 with a remainder of 207.
Put 1 as the next digit of the answer. 
Result so far: 66190.1
The remainder is 207 after subtracting 803 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 10:
If we divide 2070 by 803, we get 2 and a remainder of 464.
The number 2 becomes the next digit in our result. 
Result so far: 66190.12
The remainder is 464 after subtracting 1606 from 2070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Going ahead to step 11:
When dividing 4640 by 803, we get 5 with a remainder of 625.
Record the quotient 5 as the next digit in the result. 
Result so far: 66190.125
Deduct 4015 from 4640 and we're left with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Moving on to step 12:
The number 803 fits into 6250 7 times, leaving a remainder of 629.
The next digit of our result is 7. 
Result so far: 66190.1257
If we take 5621 away from 6250, we end up with 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

Step 13:
When dividing 6290 by 803, we get 7 with a remainder of 669.
Put 7 as the next digit of the answer. 
Result so far: 66190.12577
Deduct 5621 from 6290 and we're left with 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

The final outcome is 66190.12577, with a leftover of 0.000669.
