We look at the division of 53954862 by 766 
We're looking to find how many times 766 goes into 53954862.

Step 1:
The number 766 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 766

Going ahead to step 2:
When dividing 53 by 766, we get 0 with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 766

Going ahead to step 3:
The number 766 fits into 539 0 times, leaving a remainder of 539.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 539 after subtracting 0 from 539.
Take the next digit (5) from the dividend and append it to 539, then repeat: 5395 / 766

Advancing to step 4:
766 can be fit into 5395 7 times, resulting in a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 5362 from 5395 leaves us with 33.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 766

On to step 5:
766 goes into 334 0 times with a remainder of 334.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
The remainder is 334 after subtracting 0 from 334.
Append the next digit (8) from the dividend to 334 and continue with: 3348 / 766

Step 6:
If we divide 3348 by 766, we get 4 and a remainder of 284.
Write down 4 as next digit of the result. 
Result so far: 704.0
Subtract 3064 from 3348 to get 284.
Include the next digit (6) from the dividend after 284, then repeat: 2846 / 766

Advancing to step 7:
2846 divided by 766 is 3 with a remainder of 548.
The number 3 becomes the next digit in our result. 
Result so far: 7043.0
If we take 2298 away from 2846, we end up with 548.
Include the next digit (2) from the dividend after 548, then repeat: 5482 / 766

Moving on to step 8:
5482 divided by 766 is 7 with a remainder of 120.
Put 7 as the next digit of the answer. 
Result so far: 70437.0
Subtract 5362 from 5482 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 9:
If we divide 1200 by 766, we get 1 and a remainder of 434.
Put 1 as the next digit of the answer. 
Result so far: 70437.1
Subtracting 766 from 1200 leaves us with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

On to step 10:
766 goes into 4340 5 times with a remainder of 510.
The number 5 becomes the next digit in our result. 
Result so far: 70437.15
If we take 3830 away from 4340, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 11:
766 can be fit into 5100 6 times, resulting in a remainder of 504.
Use 6 as the next digit of our solution. 
Result so far: 70437.156
Subtract 4596 from 5100 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Let's proceed to step 12:
When dividing 5040 by 766, we get 6 with a remainder of 444.
Record the quotient 6 as the next digit in the result. 
Result so far: 70437.1566
Deduct 4596 from 5040 and we're left 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.

The final result is 70437.1566 with a remainder of 0.00444.
