926437 divided by 21 
We want to figure out the number of times 926437 can be divided by 21.

On to step 1:
21 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 21

Advancing to step 2:
92 divided by 21 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 84 away from 92, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 21

Moving on to step 3:
If we divide 86 by 21, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we subtract 84 from 86, we get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 21

Step 4:
When dividing 24 by 21, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 441.0
Deduct 21 from 24 and we're left with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 21

On to step 5:
The number 21 fits into 33 1 times, leaving a remainder of 12.
The next digit of our result is 1. 
Result so far: 4411.0
Subtracting 21 from 33 leaves us with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 21

Going ahead to step 6:
127 divided by 21 is 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 44116.0
If we subtract 126 from 127, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
When dividing 10 by 21, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 44116.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
When dividing 100 by 21, we get 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 44116.04
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
If we divide 160 by 21, we get 7 and a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 44116.047
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 10:
When dividing 130 by 21, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 44116.0476
The remainder is 4 after subtracting 126 from 130.
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 11:
21 goes into 40 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 44116.04761
Deduct 21 from 40 and we're left with 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 12:
190 divided by 21 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 44116.047619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 13:
21 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 44116.047619
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
100 divided by 21 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 44116.04761904
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 44116.04761904 with a balance of 1.6e-08.
