Let's divide 551660 by 81
We want to divide 551660 by 81.

Let's proceed to step 1:
The number 81 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 81

Step 2:
55 divided by 81 is 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Include the next digit (1) from the dividend after 55, then repeat: 551 / 81

Advancing to step 3:
551 divided by 81 is 6 with a remainder of 65.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 486 from 551, we get 65.
Bring next digit (6) of the dividend behind the 65 and repeat the process: 656 / 81

Step 4:
The number 81 fits into 656 8 times, leaving a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 68.0
If we take 648 away from 656, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 81

Advancing to step 5:
86 divided by 81 is 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 681.0
Subtract 81 from 86 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 81

Step 6:
81 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 6810.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 7:
500 divided by 81 is 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 6810.6
Subtracting 486 from 500 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
When dividing 140 by 81, we get 1 with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 6810.61
Subtract 81 from 140 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 9:
81 goes into 590 7 times with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 6810.617
If we subtract 567 from 590, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 10:
230 divided by 81 is 2 with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 6810.6172
Subtracting 162 from 230 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 11:
81 goes into 680 8 times with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 6810.61728
Subtract 648 from 680 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
81 goes into 320 3 times with a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 6810.617283
Subtract 243 from 320 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 13:
When dividing 770 by 81, we get 9 with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 6810.6172839
Subtract 729 from 770 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 14:
When dividing 410 by 81, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 6810.61728395
If we take 405 away from 410, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 6810.61728395, with a leftover of 5e-09.
