We look at the division of 42052597 by 806 
We want to figure out the number of times 42052597 can be divided by 806.

On to step 1:
When dividing 4 by 806, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 806

Advancing to step 2:
The number 806 fits into 42 0 times, leaving a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 806

Going ahead to step 3:
When dividing 420 by 806, we get 0 with a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 420, we end up with 420.
Append the next digit (5) from the dividend to 420 and continue with: 4205 / 806

Step 4:
4205 divided by 806 is 5 with a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 4030 away from 4205, we end up with 175.
Append the next digit (2) from the dividend to 175 and continue with: 1752 / 806

Let's proceed to step 5:
806 goes into 1752 2 times with a remainder of 140.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Deduct 1612 from 1752 and we're left with 140.
Grab the next digit (5) from the dividend, add it to 140, then carry on: 1405 / 806

Moving on to step 6:
The number 806 fits into 1405 1 times, leaving a remainder of 599.
Use 1 as the next digit of our solution. 
Result so far: 521.0
Subtract 806 from 1405 to get 599.
Take the next digit (9) from the dividend and append it to 599, then repeat: 5999 / 806

Step 7:
The number 806 fits into 5999 7 times, leaving a remainder of 357.
Record the quotient 7 as the next digit in the result. 
Result so far: 5217.0
Subtract 5642 from 5999 to get 357.
Fetch the next digit (7) from the dividend, attach it to 357 and continue: 3577 / 806

Going ahead to step 8:
The number 806 fits into 3577 4 times, leaving a remainder of 353.
Record the quotient 4 as the next digit in the result. 
Result so far: 52174.0
Deduct 3224 from 3577 and we're left with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Going ahead to step 9:
The number 806 fits into 3530 4 times, leaving a remainder of 306.
Record the quotient 4 as the next digit in the result. 
Result so far: 52174.4
Subtracting 3224 from 3530 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 10:
If we divide 3060 by 806, we get 3 and a remainder of 642.
Put 3 as the next digit of the answer. 
Result so far: 52174.43
Subtracting 2418 from 3060 leaves us with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Going ahead to step 11:
6420 divided by 806 is 7 with a remainder of 778.
Write down 7 as next digit of the result. 
Result so far: 52174.437
Subtracting 5642 from 6420 leaves us with 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

Let's proceed to step 12:
When dividing 7780 by 806, we get 9 with a remainder of 526.
Put 9 as the next digit of the answer. 
Result so far: 52174.4379
Subtract 7254 from 7780 to get 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Let's proceed to step 13:
5260 divided by 806 is 6 with a remainder of 424.
The number 6 becomes the next digit in our result. 
Result so far: 52174.43796
If we take 4836 away from 5260, we end up with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Advancing to step 14:
4240 divided by 806 is 5 with a remainder of 210.
Record the quotient 5 as the next digit in the result. 
Result so far: 52174.437965
The remainder is 210 after subtracting 4030 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 15:
The number 806 fits into 2100 2 times, leaving a remainder of 488.
The next digit of our result is 2. 
Result so far: 52174.4379652
Subtracting 1612 from 2100 leaves us with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Advancing to step 16:
When dividing 4880 by 806, we get 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 52174.43796526
If we take 4836 away from 4880, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 52174.43796526, with a leftover of 4.4e-08.
