Let's divide 99535498 by 21
Our goal is to divide 99535498 by 21.

Going ahead to step 1:
The number 21 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 21

Let's proceed to step 2:
21 can be fit into 99 4 times, resulting in a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 15 after subtracting 84 from 99.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 21

Going ahead to step 3:
21 goes into 155 7 times with a remainder of 8.
The next digit of our result is 7. 
Result so far: 47.0
The remainder is 8 after subtracting 147 from 155.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 21

Advancing to step 4:
If we divide 83 by 21, we get 3 and a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 473.0
The remainder is 20 after subtracting 63 from 83.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 21

Let's proceed to step 5:
If we divide 205 by 21, we get 9 and a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 4739.0
Deduct 189 from 205 and we're left with 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 21

Going ahead to step 6:
When dividing 164 by 21, we get 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 47397.0
Subtract 147 from 164 to get 17.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 21

Let's proceed to step 7:
The number 21 fits into 179 8 times, leaving a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 473978.0
Subtract 168 from 179 to get 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 21

Advancing to step 8:
21 goes into 118 5 times with a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 4739785.0
Deduct 105 from 118 and we're left 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.

Advancing to step 9:
130 divided by 21 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 4739785.6
If we subtract 126 from 130, we 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.

Advancing to step 10:
40 divided by 21 is 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 4739785.61
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.

On to step 11:
190 divided by 21 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 4739785.619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
10 divided by 21 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 4739785.619
Subtract 0 from 10 to 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.

Advancing to step 13:
100 divided by 21 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 4739785.61904
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.

Going ahead to step 14:
160 divided by 21 is 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 4739785.619047
The remainder is 13 after subtracting 147 from 160.
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 15:
21 goes into 130 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 4739785.6190476
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.

Step 16:
When dividing 40 by 21, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 4739785.61904761
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.

The final outcome is 4739785.61904761, with a leftover of 1.9e-08.
