Let's divide 44253319 by 420
We're looking to find how many times 420 goes into 44253319.

On to step 1:
If we divide 4 by 420, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 420

Step 2:
When dividing 44 by 420, we get 0 with a remainder of 44.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Grab the next digit (2) from the dividend, add it to 44, then carry on: 442 / 420

On to step 3:
420 can be fit into 442 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 420 from 442 leaves us with 22.
Take the next digit (5) from the dividend and append it to 22, then repeat: 225 / 420

Let's proceed to step 4:
420 can be fit into 225 0 times, resulting in a remainder of 225.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 225 and we're left with 225.
Include the next digit (3) from the dividend after 225, then repeat: 2253 / 420

Going ahead to step 5:
If we divide 2253 by 420, we get 5 and a remainder of 153.
Put 5 as the next digit of the answer. 
Result so far: 105.0
If we take 2100 away from 2253, we end up with 153.
Bring next digit (3) of the dividend behind the 153 and repeat the process: 1533 / 420

Advancing to step 6:
The number 420 fits into 1533 3 times, leaving a remainder of 273.
Use 3 as the next digit of our solution. 
Result so far: 1053.0
If we subtract 1260 from 1533, we get 273.
Append the next digit (1) from the dividend to 273 and continue with: 2731 / 420

Going ahead to step 7:
420 can be fit into 2731 6 times, resulting in a remainder of 211.
Write down 6 as next digit of the result. 
Result so far: 10536.0
Subtract 2520 from 2731 to get 211.
Fetch the next digit (9) from the dividend, attach it to 211 and continue: 2119 / 420

Step 8:
The number 420 fits into 2119 5 times, leaving a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 105365.0
If we subtract 2100 from 2119, 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.

On to step 9:
420 goes into 190 0 times with a remainder of 190.
Record the quotient 0 as the next digit in the result. 
Result so far: 105365.0
Subtract 0 from 190 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 10:
If we divide 1900 by 420, we get 4 and a remainder of 220.
Use 4 as the next digit of our solution. 
Result so far: 105365.04
If we take 1680 away from 1900, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 11:
When dividing 2200 by 420, we get 5 with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 105365.045
The remainder is 100 after subtracting 2100 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 12:
When dividing 1000 by 420, we get 2 with a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 105365.0452
If we subtract 840 from 1000, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
If we divide 1600 by 420, we get 3 and a remainder of 340.
Put 3 as the next digit of the answer. 
Result so far: 105365.04523
Subtract 1260 from 1600 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 14:
When dividing 3400 by 420, we get 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 105365.045238
If we take 3360 away from 3400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 15:
420 goes into 400 0 times with a remainder of 400.
The next digit of our result is 0. 
Result so far: 105365.045238
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 16:
If we divide 4000 by 420, we get 9 and a remainder of 220.
Put 9 as the next digit of the answer. 
Result so far: 105365.04523809
Subtract 3780 from 4000 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final result is 105365.04523809 with a remainder of 2.2e-07.
