45906145 ÷ 806 
Let's see how many times 806 fits into 45906145.

On to step 1:
If we divide 4 by 806, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 806

Let's proceed to step 2:
If we divide 45 by 806, we get 0 and a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Append the next digit (9) from the dividend to 45 and continue with: 459 / 806

On to step 3:
806 goes into 459 0 times with a remainder of 459.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 459, we get 459.
Bring next digit (0) of the dividend behind the 459 and repeat the process: 4590 / 806

Let's proceed to step 4:
The number 806 fits into 4590 5 times, leaving a remainder of 560.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 4030 from 4590 to get 560.
Include the next digit (6) from the dividend after 560, then repeat: 5606 / 806

Going ahead to step 5:
806 goes into 5606 6 times with a remainder of 770.
Use 6 as the next digit of our solution. 
Result so far: 56.0
The remainder is 770 after subtracting 4836 from 5606.
Fetch the next digit (1) from the dividend, attach it to 770 and continue: 7701 / 806

Moving on to step 6:
If we divide 7701 by 806, we get 9 and a remainder of 447.
Write down 9 as next digit of the result. 
Result so far: 569.0
Deduct 7254 from 7701 and we're left with 447.
Fetch the next digit (4) from the dividend, attach it to 447 and continue: 4474 / 806

Step 7:
The number 806 fits into 4474 5 times, leaving a remainder of 444.
The next digit of our result is 5. 
Result so far: 5695.0
Subtracting 4030 from 4474 leaves us with 444.
Take the next digit (5) from the dividend and append it to 444, then repeat: 4445 / 806

On to step 8:
If we divide 4445 by 806, we get 5 and a remainder of 415.
The number 5 becomes the next digit in our result. 
Result so far: 56955.0
The remainder is 415 after subtracting 4030 from 4445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

On to step 9:
The number 806 fits into 4150 5 times, leaving a remainder of 120.
The number 5 becomes the next digit in our result. 
Result so far: 56955.5
Subtracting 4030 from 4150 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 10:
1200 divided by 806 is 1 with a remainder of 394.
Put 1 as the next digit of the answer. 
Result so far: 56955.51
Subtract 806 from 1200 to get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 11:
When dividing 3940 by 806, we get 4 with a remainder of 716.
Record the quotient 4 as the next digit in the result. 
Result so far: 56955.514
If we take 3224 away from 3940, we end up with 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Step 12:
When dividing 7160 by 806, we get 8 with a remainder of 712.
The next digit of our result is 8. 
Result so far: 56955.5148
Subtracting 6448 from 7160 leaves us with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Moving on to step 13:
If we divide 7120 by 806, we get 8 and a remainder of 672.
The number 8 becomes the next digit in our result. 
Result so far: 56955.51488
Deduct 6448 from 7120 and we're left with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

The final outcome is 56955.51488, with a leftover of 0.000672.
