We divide 79879203 by 420
Our goal is to divide 79879203 by 420.

Advancing to step 1:
7 divided by 420 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 420

Moving on to step 2:
If we divide 79 by 420, we get 0 and a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Bring next digit (8) of the dividend behind the 79 and repeat the process: 798 / 420

Advancing to step 3:
When dividing 798 by 420, we get 1 with a remainder of 378.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 420 from 798 leaves us with 378.
Bring next digit (7) of the dividend behind the 378 and repeat the process: 3787 / 420

Step 4:
420 can be fit into 3787 9 times, resulting in a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 3780 from 3787 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 420

Step 5:
If we divide 79 by 420, we get 0 and a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 190.0
The remainder is 79 after subtracting 0 from 79.
Take the next digit (2) from the dividend and append it to 79, then repeat: 792 / 420

Advancing to step 6:
The number 420 fits into 792 1 times, leaving a remainder of 372.
Use 1 as the next digit of our solution. 
Result so far: 1901.0
Subtract 420 from 792 to get 372.
Append the next digit (0) from the dividend to 372 and continue with: 3720 / 420

Going ahead to step 7:
3720 divided by 420 is 8 with a remainder of 360.
The next digit of our result is 8. 
Result so far: 19018.0
If we subtract 3360 from 3720, we get 360.
Include the next digit (3) from the dividend after 360, then repeat: 3603 / 420

Step 8:
If we divide 3603 by 420, we get 8 and a remainder of 243.
The next digit of our result is 8. 
Result so far: 190188.0
Deduct 3360 from 3603 and we're left with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Advancing to step 9:
420 can be fit into 2430 5 times, resulting in a remainder of 330.
The next digit of our result is 5. 
Result so far: 190188.5
Subtracting 2100 from 2430 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 10:
When dividing 3300 by 420, we get 7 with a remainder of 360.
Put 7 as the next digit of the answer. 
Result so far: 190188.57
The remainder is 360 after subtracting 2940 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 11:
When dividing 3600 by 420, we get 8 with a remainder of 240.
Put 8 as the next digit of the answer. 
Result so far: 190188.578
If we subtract 3360 from 3600, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 12:
2400 divided by 420 is 5 with a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 190188.5785
The remainder is 300 after subtracting 2100 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 13:
3000 divided by 420 is 7 with a remainder of 60.
The next digit of our result is 7. 
Result so far: 190188.57857
If we take 2940 away from 3000, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
The number 420 fits into 600 1 times, leaving a remainder of 180.
Record the quotient 1 as the next digit in the result. 
Result so far: 190188.578571
If we take 420 away from 600, we end up 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.

Going ahead to step 15:
1800 divided by 420 is 4 with a remainder of 120.
Put 4 as the next digit of the answer. 
Result so far: 190188.5785714
The remainder is 120 after subtracting 1680 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 16:
1200 divided by 420 is 2 with a remainder of 360.
The next digit of our result is 2. 
Result so far: 190188.57857142
If we take 840 away from 1200, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

After the division, we end up with 190188.57857142 and a remainder of 3.6e-07.
