We divide 81639610 by 940
Our goal is to divide 81639610 by 940.

Step 1:
When dividing 8 by 940, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 940

Step 2:
81 divided by 940 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Grab the next digit (6) from the dividend, add it to 81, then carry on: 816 / 940

Moving on to step 3:
816 divided by 940 is 0 with a remainder of 816.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 816 to get 816.
Bring next digit (3) of the dividend behind the 816 and repeat the process: 8163 / 940

Step 4:
If we divide 8163 by 940, we get 8 and a remainder of 643.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 7520 from 8163 to get 643.
Fetch the next digit (9) from the dividend, attach it to 643 and continue: 6439 / 940

Moving on to step 5:
940 can be fit into 6439 6 times, resulting in a remainder of 799.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Subtracting 5640 from 6439 leaves us with 799.
Grab the next digit (6) from the dividend, add it to 799, then carry on: 7996 / 940

Let's proceed to step 6:
When dividing 7996 by 940, we get 8 with a remainder of 476.
Put 8 as the next digit of the answer. 
Result so far: 868.0
The remainder is 476 after subtracting 7520 from 7996.
Fetch the next digit (1) from the dividend, attach it to 476 and continue: 4761 / 940

Let's proceed to step 7:
940 goes into 4761 5 times with a remainder of 61.
Use 5 as the next digit of our solution. 
Result so far: 8685.0
If we subtract 4700 from 4761, we get 61.
Grab the next digit (0) from the dividend, add it to 61, then carry on: 610 / 940

Going ahead to step 8:
940 goes into 610 0 times with a remainder of 610.
Put 0 as the next digit of the answer. 
Result so far: 86850.0
Subtracting 0 from 610 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Step 9:
If we divide 6100 by 940, we get 6 and a remainder of 460.
Use 6 as the next digit of our solution. 
Result so far: 86850.6
Deduct 5640 from 6100 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 10:
When dividing 4600 by 940, we get 4 with a remainder of 840.
Record the quotient 4 as the next digit in the result. 
Result so far: 86850.64
Subtract 3760 from 4600 to get 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

On to step 11:
The number 940 fits into 8400 8 times, leaving a remainder of 880.
Use 8 as the next digit of our solution. 
Result so far: 86850.648
Subtract 7520 from 8400 to get 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

On to step 12:
8800 divided by 940 is 9 with a remainder of 340.
The number 9 becomes the next digit in our result. 
Result so far: 86850.6489
If we take 8460 away from 8800, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 13:
940 goes into 3400 3 times with a remainder of 580.
The next digit of our result is 3. 
Result so far: 86850.64893
If we subtract 2820 from 3400, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 14:
If we divide 5800 by 940, we get 6 and a remainder of 160.
Put 6 as the next digit of the answer. 
Result so far: 86850.648936
Subtracting 5640 from 5800 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 15:
940 goes into 1600 1 times with a remainder of 660.
The next digit of our result is 1. 
Result so far: 86850.6489361
If we subtract 940 from 1600, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 16:
6600 divided by 940 is 7 with a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 86850.64893617
If we take 6580 away from 6600, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 86850.64893617 and a remainder of 2e-08.
