We look at the division of 92746638 by 21 
Let's see how many times 21 fits into 92746638.

On to step 1:
When dividing 9 by 21, we get 0 with 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.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 21

Advancing to step 2:
The number 21 fits into 92 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 84 from 92 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 21

On to step 3:
When dividing 87 by 21, we get 4 with a remainder of 3.
The next digit of our result is 4. 
Result so far: 44.0
Deduct 84 from 87 and we're left with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 21

Going ahead to step 4:
34 divided by 21 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 441.0
The remainder is 13 after subtracting 21 from 34.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 21

Step 5:
21 goes into 136 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 4416.0
If we take 126 away from 136, we end up with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 21

Advancing to step 6:
21 can be fit into 106 5 times, resulting in a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 44165.0
Subtract 105 from 106 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 21

Going ahead to step 7:
If we divide 13 by 21, we get 0 and a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 441650.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 21

Moving on to step 8:
138 divided by 21 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 4416506.0
If we take 126 away from 138, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
21 goes into 120 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 4416506.5
Deduct 105 from 120 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
21 goes into 150 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 4416506.57
Deduct 147 from 150 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
21 goes into 30 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 4416506.571
Subtract 21 from 30 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 12:
90 divided by 21 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4416506.5714
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
The number 21 fits into 60 2 times, leaving a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 4416506.57142
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 14:
21 goes into 180 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 4416506.571428
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 15:
21 goes into 120 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 4416506.5714285
The remainder is 15 after subtracting 105 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 16:
If we divide 150 by 21, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 4416506.57142857
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 4416506.57142857 with a balance of 3e-09.
