We look at the division of 51669759 by 801 
Our goal is to divide 51669759 by 801.

Advancing to step 1:
When dividing 5 by 801, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 801

Moving on to step 2:
The number 801 fits into 51 0 times, leaving a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Bring next digit (6) of the dividend behind the 51 and repeat the process: 516 / 801

Moving on to step 3:
801 goes into 516 0 times with a remainder of 516.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 516 and we're left with 516.
Append the next digit (6) from the dividend to 516 and continue with: 5166 / 801

Let's proceed to step 4:
The number 801 fits into 5166 6 times, leaving a remainder of 360.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 360 after subtracting 4806 from 5166.
Fetch the next digit (9) from the dividend, attach it to 360 and continue: 3609 / 801

On to step 5:
3609 divided by 801 is 4 with a remainder of 405.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtracting 3204 from 3609 leaves us with 405.
Take the next digit (7) from the dividend and append it to 405, then repeat: 4057 / 801

Going ahead to step 6:
If we divide 4057 by 801, we get 5 and a remainder of 52.
The number 5 becomes the next digit in our result. 
Result so far: 645.0
The remainder is 52 after subtracting 4005 from 4057.
Include the next digit (5) from the dividend after 52, then repeat: 525 / 801

Step 7:
When dividing 525 by 801, we get 0 with a remainder of 525.
The number 0 becomes the next digit in our result. 
Result so far: 6450.0
The remainder is 525 after subtracting 0 from 525.
Fetch the next digit (9) from the dividend, attach it to 525 and continue: 5259 / 801

Let's proceed to step 8:
If we divide 5259 by 801, we get 6 and a remainder of 453.
The number 6 becomes the next digit in our result. 
Result so far: 64506.0
If we take 4806 away from 5259, we end up with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Going ahead to step 9:
801 can be fit into 4530 5 times, resulting in a remainder of 525.
Record the quotient 5 as the next digit in the result. 
Result so far: 64506.5
Deduct 4005 from 4530 and we're left with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Let's proceed to step 10:
5250 divided by 801 is 6 with a remainder of 444.
The number 6 becomes the next digit in our result. 
Result so far: 64506.56
Subtracting 4806 from 5250 leaves us with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Moving on to step 11:
If we divide 4440 by 801, we get 5 and a remainder of 435.
Record the quotient 5 as the next digit in the result. 
Result so far: 64506.565
Deduct 4005 from 4440 and we're left with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

On to step 12:
801 goes into 4350 5 times with a remainder of 345.
Use 5 as the next digit of our solution. 
Result so far: 64506.5655
Subtract 4005 from 4350 to get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

The final outcome is 64506.5655, with a leftover of 0.00345.
