We look at the division of 5380889 by 661 
Our goal is to divide 5380889 by 661.

Moving on to step 1:
If we divide 5 by 661, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 661

Step 2:
53 divided by 661 is 0 with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Append the next digit (8) from the dividend to 53 and continue with: 538 / 661

Step 3:
The number 661 fits into 538 0 times, leaving a remainder of 538.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 538 after subtracting 0 from 538.
Grab the next digit (0) from the dividend, add it to 538, then carry on: 5380 / 661

On to step 4:
When dividing 5380 by 661, we get 8 with a remainder of 92.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 5288 from 5380 leaves us with 92.
Bring next digit (8) of the dividend behind the 92 and repeat the process: 928 / 661

On to step 5:
When dividing 928 by 661, we get 1 with a remainder of 267.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we subtract 661 from 928, we get 267.
Bring next digit (8) of the dividend behind the 267 and repeat the process: 2678 / 661

Moving on to step 6:
The number 661 fits into 2678 4 times, leaving a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 814.0
If we subtract 2644 from 2678, we get 34.
Take the next digit (9) from the dividend and append it to 34, then repeat: 349 / 661

Let's proceed to step 7:
The number 661 fits into 349 0 times, leaving a remainder of 349.
Write down 0 as next digit of the result. 
Result so far: 8140.0
If we subtract 0 from 349, we get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Advancing to step 8:
If we divide 3490 by 661, we get 5 and a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 8140.5
If we take 3305 away from 3490, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 9:
When dividing 1850 by 661, we get 2 with a remainder of 528.
Record the quotient 2 as the next digit in the result. 
Result so far: 8140.52
If we take 1322 away from 1850, we end up with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Let's proceed to step 10:
The number 661 fits into 5280 7 times, leaving a remainder of 653.
Use 7 as the next digit of our solution. 
Result so far: 8140.527
If we take 4627 away from 5280, we end up with 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

Advancing to step 11:
When dividing 6530 by 661, we get 9 with a remainder of 581.
The number 9 becomes the next digit in our result. 
Result so far: 8140.5279
Deduct 5949 from 6530 and we're left with 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Step 12:
661 goes into 5810 8 times with a remainder of 522.
Use 8 as the next digit of our solution. 
Result so far: 8140.52798
The remainder is 522 after subtracting 5288 from 5810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Moving on to step 13:
If we divide 5220 by 661, we get 7 and a remainder of 593.
The next digit of our result is 7. 
Result so far: 8140.527987
If we take 4627 away from 5220, we end up with 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

On to step 14:
If we divide 5930 by 661, we get 8 and a remainder of 642.
The number 8 becomes the next digit in our result. 
Result so far: 8140.5279878
If we take 5288 away from 5930, we end up 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.

Advancing to step 15:
If we divide 6420 by 661, we get 9 and a remainder of 471.
The number 9 becomes the next digit in our result. 
Result so far: 8140.52798789
Deduct 5949 from 6420 and we're left with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

The quotient of the division is 8140.52798789, and the remainder is 4.71e-07.
