637977 divided by 81 
We want to divide 637977 by 81.

On to step 1:
6 divided by 81 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 81

Moving on to step 2:
81 goes into 63 0 times with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Bring next digit (7) of the dividend behind the 63 and repeat the process: 637 / 81

Moving on to step 3:
637 divided by 81 is 7 with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 567 away from 637, we end up with 70.
Fetch the next digit (9) from the dividend, attach it to 70 and continue: 709 / 81

On to step 4:
81 can be fit into 709 8 times, resulting in a remainder of 61.
Write down 8 as next digit of the result. 
Result so far: 78.0
If we subtract 648 from 709, we get 61.
Fetch the next digit (7) from the dividend, attach it to 61 and continue: 617 / 81

Going ahead to step 5:
When dividing 617 by 81, we get 7 with a remainder of 50.
Write down 7 as next digit of the result. 
Result so far: 787.0
If we take 567 away from 617, we end up with 50.
Bring next digit (7) of the dividend behind the 50 and repeat the process: 507 / 81

Step 6:
If we divide 507 by 81, we get 6 and a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 7876.0
Subtract 486 from 507 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
81 goes into 210 2 times with a remainder of 48.
The next digit of our result is 2. 
Result so far: 7876.2
Subtract 162 from 210 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 8:
81 goes into 480 5 times with a remainder of 75.
The next digit of our result is 5. 
Result so far: 7876.25
If we take 405 away from 480, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 9:
When dividing 750 by 81, we get 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 7876.259
The remainder is 21 after subtracting 729 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 10:
81 goes into 210 2 times with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 7876.2592
Deduct 162 from 210 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
81 goes into 480 5 times with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 7876.25925
The remainder is 75 after subtracting 405 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 12:
750 divided by 81 is 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 7876.259259
If we subtract 729 from 750, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 13:
When dividing 210 by 81, we get 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 7876.2592592
Subtracting 162 from 210 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
480 divided by 81 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 7876.25925925
Subtract 405 from 480 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

After the division, we end up with 7876.25925925 and a remainder of 7.5e-08.
