Let's divide 82161433 by 420
We want to divide 82161433 by 420.

On to step 1:
If we divide 8 by 420, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 420

On to step 2:
When dividing 82 by 420, we get 0 with a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 82, we end up with 82.
Bring next digit (1) of the dividend behind the 82 and repeat the process: 821 / 420

Advancing to step 3:
420 goes into 821 1 times with a remainder of 401.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 420 from 821, we get 401.
Include the next digit (6) from the dividend after 401, then repeat: 4016 / 420

Moving on to step 4:
420 can be fit into 4016 9 times, resulting in a remainder of 236.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 3780 from 4016 leaves us with 236.
Take the next digit (1) from the dividend and append it to 236, then repeat: 2361 / 420

Let's proceed to step 5:
420 can be fit into 2361 5 times, resulting in a remainder of 261.
The number 5 becomes the next digit in our result. 
Result so far: 195.0
Subtract 2100 from 2361 to get 261.
Take the next digit (4) from the dividend and append it to 261, then repeat: 2614 / 420

Moving on to step 6:
2614 divided by 420 is 6 with a remainder of 94.
Use 6 as the next digit of our solution. 
Result so far: 1956.0
If we subtract 2520 from 2614, we get 94.
Grab the next digit (3) from the dividend, add it to 94, then carry on: 943 / 420

On to step 7:
When dividing 943 by 420, we get 2 with a remainder of 103.
Record the quotient 2 as the next digit in the result. 
Result so far: 19562.0
If we take 840 away from 943, we end up with 103.
Grab the next digit (3) from the dividend, add it to 103, then carry on: 1033 / 420

Going ahead to step 8:
When dividing 1033 by 420, we get 2 with a remainder of 193.
Put 2 as the next digit of the answer. 
Result so far: 195622.0
Subtracting 840 from 1033 leaves us with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Let's proceed to step 9:
420 goes into 1930 4 times with a remainder of 250.
The number 4 becomes the next digit in our result. 
Result so far: 195622.4
Subtracting 1680 from 1930 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 10:
420 goes into 2500 5 times with a remainder of 400.
Use 5 as the next digit of our solution. 
Result so far: 195622.45
Deduct 2100 from 2500 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 11:
If we divide 4000 by 420, we get 9 and a remainder of 220.
The next digit of our result is 9. 
Result so far: 195622.459
Deduct 3780 from 4000 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 12:
420 goes into 2200 5 times with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 195622.4595
Subtracting 2100 from 2200 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 13:
If we divide 1000 by 420, we get 2 and a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 195622.45952
If we subtract 840 from 1000, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 14:
420 goes into 1600 3 times with a remainder of 340.
Put 3 as the next digit of the answer. 
Result so far: 195622.459523
Deduct 1260 from 1600 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 15:
The number 420 fits into 3400 8 times, leaving a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 195622.4595238
If we take 3360 away from 3400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 16:
420 can be fit into 400 0 times, resulting in a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 195622.4595238
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 195622.4595238, and the remainder is 4e-07.
