401021 ÷ 99 
Let's see how many times 99 fits into 401021.

Moving on to step 1:
4 divided by 99 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 99

On to step 2:
If we divide 40 by 99, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 99

Moving on to step 3:
If we divide 401 by 99, we get 4 and a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 5 after subtracting 396 from 401.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 99

Advancing to step 4:
99 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtracting 0 from 50 leaves us with 50.
Include the next digit (2) from the dividend after 50, then repeat: 502 / 99

Advancing to step 5:
The number 99 fits into 502 5 times, leaving a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 405.0
Subtract 495 from 502 to get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 99

Step 6:
99 goes into 71 0 times with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 4050.0
Deduct 0 from 71 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 7:
If we divide 710 by 99, we get 7 and a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 4050.7
If we take 693 away from 710, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
When dividing 170 by 99, we get 1 with a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 4050.71
If we subtract 99 from 170, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 9:
710 divided by 99 is 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 4050.717
Subtract 693 from 710 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 10:
99 can be fit into 170 1 times, resulting in a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 4050.7171
If we take 99 away from 170, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 11:
99 can be fit into 710 7 times, resulting in a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 4050.71717
Subtract 693 from 710 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 12:
99 goes into 170 1 times with a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 4050.717171
The remainder is 71 after subtracting 99 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 13:
99 can be fit into 710 7 times, resulting in a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 4050.7171717
If we subtract 693 from 710, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 14:
When dividing 170 by 99, we get 1 with a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 4050.71717171
The remainder is 71 after subtracting 99 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Our division results in 4050.71717171 with a remaining 7.1e-08.
