Let's divide 84971952 by 420
We want to divide 84971952 by 420.

Step 1:
If we divide 8 by 420, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 420

Moving on to step 2:
84 divided by 420 is 0 with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Include the next digit (9) from the dividend after 84, then repeat: 849 / 420

Going ahead to step 3:
849 divided by 420 is 2 with a remainder of 9.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 9 after subtracting 840 from 849.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 420

Moving on to step 4:
97 divided by 420 is 0 with a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtracting 0 from 97 leaves us with 97.
Include the next digit (1) from the dividend after 97, then repeat: 971 / 420

On to step 5:
420 goes into 971 2 times with a remainder of 131.
Use 2 as the next digit of our solution. 
Result so far: 202.0
If we subtract 840 from 971, we get 131.
Take the next digit (9) from the dividend and append it to 131, then repeat: 1319 / 420

Advancing to step 6:
The number 420 fits into 1319 3 times, leaving a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 2023.0
If we subtract 1260 from 1319, we get 59.
Include the next digit (5) from the dividend after 59, then repeat: 595 / 420

Let's proceed to step 7:
420 goes into 595 1 times with a remainder of 175.
Write down 1 as next digit of the result. 
Result so far: 20231.0
Deduct 420 from 595 and we're left with 175.
Take the next digit (2) from the dividend and append it to 175, then repeat: 1752 / 420

Moving on to step 8:
If we divide 1752 by 420, we get 4 and a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 202314.0
Deduct 1680 from 1752 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
If we divide 720 by 420, we get 1 and a remainder of 300.
The next digit of our result is 1. 
Result so far: 202314.1
If we subtract 420 from 720, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 10:
When dividing 3000 by 420, we get 7 with a remainder of 60.
Use 7 as the next digit of our solution. 
Result so far: 202314.17
The remainder is 60 after subtracting 2940 from 3000.
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 11:
If we divide 600 by 420, we get 1 and a remainder of 180.
Record the quotient 1 as the next digit in the result. 
Result so far: 202314.171
Deduct 420 from 600 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.

Step 12:
If we divide 1800 by 420, we get 4 and a remainder of 120.
The number 4 becomes the next digit in our result. 
Result so far: 202314.1714
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.

Step 13:
420 can be fit into 1200 2 times, resulting in a remainder of 360.
Record the quotient 2 as the next digit in the result. 
Result so far: 202314.17142
If we subtract 840 from 1200, we get 360.
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 14:
420 can be fit into 3600 8 times, resulting in a remainder of 240.
Write down 8 as next digit of the result. 
Result so far: 202314.171428
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.

Advancing to step 15:
420 can be fit into 2400 5 times, resulting in a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 202314.1714285
Subtracting 2100 from 2400 leaves us with 300.
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 16:
3000 divided by 420 is 7 with a remainder of 60.
Use 7 as the next digit of our solution. 
Result so far: 202314.17142857
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.

The quotient of the division is 202314.17142857, and the remainder is 6e-08.
