We're dividing 79164713 by 420 
We want to divide 79164713 by 420.

Moving on to step 1:
The number 420 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 420

Moving on to step 2:
79 divided by 420 is 0 with a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Fetch the next digit (1) from the dividend, attach it to 79 and continue: 791 / 420

Advancing to step 3:
If we divide 791 by 420, we get 1 and a remainder of 371.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 420 from 791 leaves us with 371.
Include the next digit (6) from the dividend after 371, then repeat: 3716 / 420

Moving on to step 4:
The number 420 fits into 3716 8 times, leaving a remainder of 356.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 356 after subtracting 3360 from 3716.
Grab the next digit (4) from the dividend, add it to 356, then carry on: 3564 / 420

Let's proceed to step 5:
The number 420 fits into 3564 8 times, leaving a remainder of 204.
Write down 8 as next digit of the result. 
Result so far: 188.0
If we take 3360 away from 3564, we end up with 204.
Append the next digit (7) from the dividend to 204 and continue with: 2047 / 420

Moving on to step 6:
When dividing 2047 by 420, we get 4 with a remainder of 367.
Write down 4 as next digit of the result. 
Result so far: 1884.0
The remainder is 367 after subtracting 1680 from 2047.
Include the next digit (1) from the dividend after 367, then repeat: 3671 / 420

Moving on to step 7:
420 goes into 3671 8 times with a remainder of 311.
The next digit of our result is 8. 
Result so far: 18848.0
The remainder is 311 after subtracting 3360 from 3671.
Grab the next digit (3) from the dividend, add it to 311, then carry on: 3113 / 420

Advancing to step 8:
The number 420 fits into 3113 7 times, leaving a remainder of 173.
Write down 7 as next digit of the result. 
Result so far: 188487.0
If we subtract 2940 from 3113, we get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Advancing to step 9:
420 can be fit into 1730 4 times, resulting in a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 188487.4
If we subtract 1680 from 1730, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
420 can be fit into 500 1 times, resulting in a remainder of 80.
Write down 1 as next digit of the result. 
Result so far: 188487.41
Deduct 420 from 500 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
The number 420 fits into 800 1 times, leaving a remainder of 380.
The next digit of our result is 1. 
Result so far: 188487.411
If we subtract 420 from 800, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

After the division, we end up with 188487.411 and a remainder of 0.038.
