80932237 ÷ 420 
We want to divide 80932237 by 420.

Let's proceed to step 1:
The number 420 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 420

Step 2:
420 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Take the next digit (9) from the dividend and append it to 80, then repeat: 809 / 420

Moving on to step 3:
When dividing 809 by 420, we get 1 with a remainder of 389.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 420 away from 809, we end up with 389.
Append the next digit (3) from the dividend to 389 and continue with: 3893 / 420

On to step 4:
420 goes into 3893 9 times with a remainder of 113.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 3780 from 3893 and we're left with 113.
Bring next digit (2) of the dividend behind the 113 and repeat the process: 1132 / 420

Moving on to step 5:
When dividing 1132 by 420, we get 2 with a remainder of 292.
The number 2 becomes the next digit in our result. 
Result so far: 192.0
Deduct 840 from 1132 and we're left with 292.
Fetch the next digit (2) from the dividend, attach it to 292 and continue: 2922 / 420

Step 6:
The number 420 fits into 2922 6 times, leaving a remainder of 402.
The number 6 becomes the next digit in our result. 
Result so far: 1926.0
Subtract 2520 from 2922 to get 402.
Fetch the next digit (3) from the dividend, attach it to 402 and continue: 4023 / 420

Going ahead to step 7:
420 can be fit into 4023 9 times, resulting in a remainder of 243.
The next digit of our result is 9. 
Result so far: 19269.0
The remainder is 243 after subtracting 3780 from 4023.
Take the next digit (7) from the dividend and append it to 243, then repeat: 2437 / 420

Step 8:
If we divide 2437 by 420, we get 5 and a remainder of 337.
Use 5 as the next digit of our solution. 
Result so far: 192695.0
Subtract 2100 from 2437 to get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Let's proceed to step 9:
When dividing 3370 by 420, we get 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 192695.8
If we subtract 3360 from 3370, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
420 can be fit into 100 0 times, resulting in a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 192695.8
Subtracting 0 from 100 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 11:
The number 420 fits into 1000 2 times, leaving a remainder of 160.
Record the quotient 2 as the next digit in the result. 
Result so far: 192695.802
Subtract 840 from 1000 to 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.

Let's proceed to step 12:
420 can be fit into 1600 3 times, resulting in a remainder of 340.
The next digit of our result is 3. 
Result so far: 192695.8023
If we subtract 1260 from 1600, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 13:
The number 420 fits into 3400 8 times, leaving a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 192695.80238
The remainder is 40 after subtracting 3360 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
420 can be fit into 400 0 times, resulting in a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 192695.80238
If we take 0 away from 400, we end up 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.

On to step 15:
The number 420 fits into 4000 9 times, leaving a remainder of 220.
The number 9 becomes the next digit in our result. 
Result so far: 192695.8023809
If we take 3780 away from 4000, we end up 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 16:
2200 divided by 420 is 5 with a remainder of 100.
The next digit of our result is 5. 
Result so far: 192695.80238095
Subtract 2100 from 2200 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 192695.80238095 with a remainder of 1e-07.
