981154 divided by 21 
We want to figure out the number of times 981154 can be divided by 21.

Moving on to step 1:
The number 21 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 21

Let's proceed to step 2:
21 can be fit into 98 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 84 from 98 to get 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 21

Moving on to step 3:
21 goes into 141 6 times with a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 46.0
Deduct 126 from 141 and we're left with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 21

Going ahead to step 4:
The number 21 fits into 151 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 467.0
The remainder is 4 after subtracting 147 from 151.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 21

Moving on to step 5:
If we divide 45 by 21, we get 2 and a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 4672.0
The remainder is 3 after subtracting 42 from 45.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 21

On to step 6:
When dividing 34 by 21, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 46721.0
Subtract 21 from 34 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:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 46721.6
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.

Step 8:
The number 21 fits into 40 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 46721.61
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.

Step 9:
190 divided by 21 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 46721.619
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.

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: 46721.619
Subtracting 0 from 10 leaves us 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.

On to step 11:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 46721.61904
If we subtract 84 from 100, we 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.

Moving on to step 12:
21 goes into 160 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 46721.619047
If we subtract 147 from 160, we 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.

Let's proceed to step 13:
21 goes into 130 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 46721.6190476
Deduct 126 from 130 and we're left 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.

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: 46721.61904761
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.

The final result is 46721.61904761 with a remainder of 1.9e-08.
