We're dividing 73819669 by 420 
We're looking to find how many times 420 goes into 73819669.

Let's proceed to step 1:
7 divided by 420 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 420

Let's proceed to step 2:
If we divide 73 by 420, we get 0 and a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Include the next digit (8) from the dividend after 73, then repeat: 738 / 420

Moving on to step 3:
When dividing 738 by 420, we get 1 with a remainder of 318.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 420 from 738 and we're left with 318.
Take the next digit (1) from the dividend and append it to 318, then repeat: 3181 / 420

On to step 4:
The number 420 fits into 3181 7 times, leaving a remainder of 241.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 2940 from 3181, we get 241.
Fetch the next digit (9) from the dividend, attach it to 241 and continue: 2419 / 420

On to step 5:
The number 420 fits into 2419 5 times, leaving a remainder of 319.
Use 5 as the next digit of our solution. 
Result so far: 175.0
The remainder is 319 after subtracting 2100 from 2419.
Take the next digit (6) from the dividend and append it to 319, then repeat: 3196 / 420

Moving on to step 6:
When dividing 3196 by 420, we get 7 with a remainder of 256.
Write down 7 as next digit of the result. 
Result so far: 1757.0
Deduct 2940 from 3196 and we're left with 256.
Bring next digit (6) of the dividend behind the 256 and repeat the process: 2566 / 420

On to step 7:
2566 divided by 420 is 6 with a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 17576.0
Subtract 2520 from 2566 to get 46.
Grab the next digit (9) from the dividend, add it to 46, then carry on: 469 / 420

Let's proceed to step 8:
469 divided by 420 is 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 175761.0
Subtracting 420 from 469 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
If we divide 490 by 420, we get 1 and a remainder of 70.
The next digit of our result is 1. 
Result so far: 175761.1
If we subtract 420 from 490, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
420 goes into 700 1 times with a remainder of 280.
Use 1 as the next digit of our solution. 
Result so far: 175761.11
Subtracting 420 from 700 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

After the division, we end up with 175761.11 and a remainder of 0.28.
