We're dividing 7122021 by 442 
Let's see how many times 442 fits into 7122021.

Let's proceed to step 1:
When dividing 7 by 442, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 442

Step 2:
The number 442 fits into 71 0 times, leaving a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Take the next digit (2) from the dividend and append it to 71, then repeat: 712 / 442

Going ahead to step 3:
The number 442 fits into 712 1 times, leaving a remainder of 270.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 442 from 712, we get 270.
Include the next digit (2) from the dividend after 270, then repeat: 2702 / 442

Step 4:
442 goes into 2702 6 times with a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 2652 from 2702, we get 50.
Take the next digit (0) from the dividend and append it to 50, then repeat: 500 / 442

Going ahead to step 5:
When dividing 500 by 442, we get 1 with a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 161.0
If we take 442 away from 500, we end up with 58.
Grab the next digit (2) from the dividend, add it to 58, then carry on: 582 / 442

Let's proceed to step 6:
If we divide 582 by 442, we get 1 and a remainder of 140.
Record the quotient 1 as the next digit in the result. 
Result so far: 1611.0
Subtract 442 from 582 to get 140.
Bring next digit (1) of the dividend behind the 140 and repeat the process: 1401 / 442

Going ahead to step 7:
If we divide 1401 by 442, we get 3 and a remainder of 75.
The next digit of our result is 3. 
Result so far: 16113.0
Deduct 1326 from 1401 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 8:
750 divided by 442 is 1 with a remainder of 308.
Record the quotient 1 as the next digit in the result. 
Result so far: 16113.1
Subtracting 442 from 750 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 9:
When dividing 3080 by 442, we get 6 with a remainder of 428.
Use 6 as the next digit of our solution. 
Result so far: 16113.16
If we subtract 2652 from 3080, we get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 10:
If we divide 4280 by 442, we get 9 and a remainder of 302.
Record the quotient 9 as the next digit in the result. 
Result so far: 16113.169
The remainder is 302 after subtracting 3978 from 4280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Advancing to step 11:
When dividing 3020 by 442, we get 6 with a remainder of 368.
Use 6 as the next digit of our solution. 
Result so far: 16113.1696
The remainder is 368 after subtracting 2652 from 3020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 12:
442 goes into 3680 8 times with a remainder of 144.
The number 8 becomes the next digit in our result. 
Result so far: 16113.16968
If we subtract 3536 from 3680, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 13:
When dividing 1440 by 442, we get 3 with a remainder of 114.
The next digit of our result is 3. 
Result so far: 16113.169683
Subtract 1326 from 1440 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 14:
The number 442 fits into 1140 2 times, leaving a remainder of 256.
Put 2 as the next digit of the answer. 
Result so far: 16113.1696832
Deduct 884 from 1140 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 15:
The number 442 fits into 2560 5 times, leaving a remainder of 350.
The number 5 becomes the next digit in our result. 
Result so far: 16113.16968325
If we take 2210 away from 2560, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

The final outcome is 16113.16968325, with a leftover of 3.5e-07.
