We look at the division of 45058186 by 803 
Our goal is to divide 45058186 by 803.

Going ahead to step 1:
803 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 803

On to step 2:
When dividing 45 by 803, we get 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Grab the next digit (0) from the dividend, add it to 45, then carry on: 450 / 803

Advancing to step 3:
The number 803 fits into 450 0 times, leaving a remainder of 450.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 450 after subtracting 0 from 450.
Append the next digit (5) from the dividend to 450 and continue with: 4505 / 803

On to step 4:
If we divide 4505 by 803, we get 5 and a remainder of 490.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 4015 away from 4505, we end up with 490.
Append the next digit (8) from the dividend to 490 and continue with: 4908 / 803

Step 5:
When dividing 4908 by 803, we get 6 with a remainder of 90.
Put 6 as the next digit of the answer. 
Result so far: 56.0
Deduct 4818 from 4908 and we're left with 90.
Fetch the next digit (1) from the dividend, attach it to 90 and continue: 901 / 803

On to step 6:
901 divided by 803 is 1 with a remainder of 98.
Use 1 as the next digit of our solution. 
Result so far: 561.0
If we subtract 803 from 901, we get 98.
Bring next digit (8) of the dividend behind the 98 and repeat the process: 988 / 803

Moving on to step 7:
803 goes into 988 1 times with a remainder of 185.
Record the quotient 1 as the next digit in the result. 
Result so far: 5611.0
Subtract 803 from 988 to get 185.
Grab the next digit (6) from the dividend, add it to 185, then carry on: 1856 / 803

Let's proceed to step 8:
The number 803 fits into 1856 2 times, leaving a remainder of 250.
The next digit of our result is 2. 
Result so far: 56112.0
The remainder is 250 after subtracting 1606 from 1856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 9:
When dividing 2500 by 803, we get 3 with a remainder of 91.
Use 3 as the next digit of our solution. 
Result so far: 56112.3
Deduct 2409 from 2500 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 10:
When dividing 910 by 803, we get 1 with a remainder of 107.
Use 1 as the next digit of our solution. 
Result so far: 56112.31
Subtracting 803 from 910 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Step 11:
If we divide 1070 by 803, we get 1 and a remainder of 267.
Write down 1 as next digit of the result. 
Result so far: 56112.311
Deduct 803 from 1070 and we're left with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Our division results in 56112.311 with a remaining 0.0267.
