Let's divide 74179326 by 420
Our goal is to divide 74179326 by 420.

Let's proceed to step 1:
If we divide 7 by 420, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 420

Step 2:
74 divided by 420 is 0 with a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Take the next digit (1) from the dividend and append it to 74, then repeat: 741 / 420

Going ahead to step 3:
When dividing 741 by 420, we get 1 with a remainder of 321.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 420 from 741, we get 321.
Bring next digit (7) of the dividend behind the 321 and repeat the process: 3217 / 420

Let's proceed to step 4:
3217 divided by 420 is 7 with a remainder of 277.
Use 7 as the next digit of our solution. 
Result so far: 17.0
The remainder is 277 after subtracting 2940 from 3217.
Grab the next digit (9) from the dividend, add it to 277, then carry on: 2779 / 420

Let's proceed to step 5:
420 can be fit into 2779 6 times, resulting in a remainder of 259.
The number 6 becomes the next digit in our result. 
Result so far: 176.0
If we subtract 2520 from 2779, we get 259.
Bring next digit (3) of the dividend behind the 259 and repeat the process: 2593 / 420

On to step 6:
If we divide 2593 by 420, we get 6 and a remainder of 73.
Use 6 as the next digit of our solution. 
Result so far: 1766.0
If we take 2520 away from 2593, we end up with 73.
Append the next digit (2) from the dividend to 73 and continue with: 732 / 420

Going ahead to step 7:
The number 420 fits into 732 1 times, leaving a remainder of 312.
Put 1 as the next digit of the answer. 
Result so far: 17661.0
If we take 420 away from 732, we end up with 312.
Grab the next digit (6) from the dividend, add it to 312, then carry on: 3126 / 420

Going ahead to step 8:
3126 divided by 420 is 7 with a remainder of 186.
The next digit of our result is 7. 
Result so far: 176617.0
Deduct 2940 from 3126 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 9:
If we divide 1860 by 420, we get 4 and a remainder of 180.
Record the quotient 4 as the next digit in the result. 
Result so far: 176617.4
Deduct 1680 from 1860 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 10:
1800 divided by 420 is 4 with a remainder of 120.
Use 4 as the next digit of our solution. 
Result so far: 176617.44
Subtracting 1680 from 1800 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 176617.44 with a remainder of 0.12.
