43354536 ÷ 820 
We want to figure out the number of times 43354536 can be divided by 820.

On to step 1:
4 divided by 820 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 820

Let's proceed to step 2:
43 divided by 820 is 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Take the next digit (3) from the dividend and append it to 43, then repeat: 433 / 820

Let's proceed to step 3:
820 can be fit into 433 0 times, resulting in a remainder of 433.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 433 to get 433.
Grab the next digit (5) from the dividend, add it to 433, then carry on: 4335 / 820

On to step 4:
The number 820 fits into 4335 5 times, leaving a remainder of 235.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 4100 from 4335 leaves us with 235.
Bring next digit (4) of the dividend behind the 235 and repeat the process: 2354 / 820

On to step 5:
820 can be fit into 2354 2 times, resulting in a remainder of 714.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Subtracting 1640 from 2354 leaves us with 714.
Append the next digit (5) from the dividend to 714 and continue with: 7145 / 820

Going ahead to step 6:
820 goes into 7145 8 times with a remainder of 585.
Record the quotient 8 as the next digit in the result. 
Result so far: 528.0
Subtracting 6560 from 7145 leaves us with 585.
Grab the next digit (3) from the dividend, add it to 585, then carry on: 5853 / 820

Step 7:
The number 820 fits into 5853 7 times, leaving a remainder of 113.
The next digit of our result is 7. 
Result so far: 5287.0
Deduct 5740 from 5853 and we're left with 113.
Fetch the next digit (6) from the dividend, attach it to 113 and continue: 1136 / 820

Moving on to step 8:
820 goes into 1136 1 times with a remainder of 316.
Put 1 as the next digit of the answer. 
Result so far: 52871.0
If we take 820 away from 1136, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 9:
The number 820 fits into 3160 3 times, leaving a remainder of 700.
Put 3 as the next digit of the answer. 
Result so far: 52871.3
The remainder is 700 after subtracting 2460 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 10:
If we divide 7000 by 820, we get 8 and a remainder of 440.
The next digit of our result is 8. 
Result so far: 52871.38
Subtract 6560 from 7000 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 11:
820 goes into 4400 5 times with a remainder of 300.
The next digit of our result is 5. 
Result so far: 52871.385
If we subtract 4100 from 4400, 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.

Step 12:
If we divide 3000 by 820, we get 3 and a remainder of 540.
Write down 3 as next digit of the result. 
Result so far: 52871.3853
The remainder is 540 after subtracting 2460 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 13:
If we divide 5400 by 820, we get 6 and a remainder of 480.
The next digit of our result is 6. 
Result so far: 52871.38536
Deduct 4920 from 5400 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 14:
820 goes into 4800 5 times with a remainder of 700.
The next digit of our result is 5. 
Result so far: 52871.385365
Subtracting 4100 from 4800 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 15:
When dividing 7000 by 820, we get 8 with a remainder of 440.
Use 8 as the next digit of our solution. 
Result so far: 52871.3853658
If we subtract 6560 from 7000, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 16:
If we divide 4400 by 820, we get 5 and a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 52871.38536585
If we take 4100 away from 4400, we end up 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.

The quotient of the division is 52871.38536585, and the remainder is 3e-07.
