Let's divide 656137 by 21
We want to divide 656137 by 21.

Let's proceed to step 1:
If we divide 6 by 21, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 21

Going ahead to step 2:
21 goes into 65 3 times with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 63 from 65, we get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 21

Moving on to step 3:
If we divide 26 by 21, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
The remainder is 5 after subtracting 21 from 26.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 21

On to step 4:
51 divided by 21 is 2 with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 312.0
The remainder is 9 after subtracting 42 from 51.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 21

Let's proceed to step 5:
21 goes into 93 4 times with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 3124.0
Subtracting 84 from 93 leaves us with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 21

Moving on to step 6:
If we divide 97 by 21, we get 4 and a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 31244.0
Subtract 84 from 97 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
If we divide 130 by 21, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 31244.6
If we take 126 away from 130, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
When dividing 40 by 21, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 31244.61
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
190 divided by 21 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 31244.619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 10:
If we divide 10 by 21, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 31244.619
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
100 divided by 21 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 31244.61904
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
When dividing 160 by 21, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 31244.619047
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 13:
If we divide 130 by 21, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 31244.6190476
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
21 can be fit into 40 1 times, resulting in a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 31244.61904761
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

In conclusion, the division gives 31244.61904761 with a balance of 1.9e-08.
