45903683 ÷ 820 
Our goal is to divide 45903683 by 820.

Going ahead to step 1:
The number 820 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 820

Advancing to step 2:
820 goes into 45 0 times with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Bring next digit (9) of the dividend behind the 45 and repeat the process: 459 / 820

Let's proceed to step 3:
820 can be fit into 459 0 times, resulting in a remainder of 459.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 459, we get 459.
Grab the next digit (0) from the dividend, add it to 459, then carry on: 4590 / 820

Let's proceed to step 4:
The number 820 fits into 4590 5 times, leaving a remainder of 490.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 490 after subtracting 4100 from 4590.
Include the next digit (3) from the dividend after 490, then repeat: 4903 / 820

Advancing to step 5:
When dividing 4903 by 820, we get 5 with a remainder of 803.
Use 5 as the next digit of our solution. 
Result so far: 55.0
Subtract 4100 from 4903 to get 803.
Append the next digit (6) from the dividend to 803 and continue with: 8036 / 820

Advancing to step 6:
820 can be fit into 8036 9 times, resulting in a remainder of 656.
Use 9 as the next digit of our solution. 
Result so far: 559.0
If we take 7380 away from 8036, we end up with 656.
Fetch the next digit (8) from the dividend, attach it to 656 and continue: 6568 / 820

On to step 7:
6568 divided by 820 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 5598.0
Deduct 6560 from 6568 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 820

Advancing to step 8:
If we divide 83 by 820, we get 0 and a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 55980.0
Deduct 0 from 83 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 9:
When dividing 830 by 820, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 55980.1
Subtracting 820 from 830 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
The number 820 fits into 100 0 times, leaving a remainder of 100.
The next digit of our result is 0. 
Result so far: 55980.1
Deduct 0 from 100 and we're left 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.

Let's proceed to step 11:
1000 divided by 820 is 1 with a remainder of 180.
Record the quotient 1 as the next digit in the result. 
Result so far: 55980.101
Subtracting 820 from 1000 leaves us 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.

Advancing to step 12:
If we divide 1800 by 820, we get 2 and a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 55980.1012
Subtracting 1640 from 1800 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 13:
When dividing 1600 by 820, we get 1 with a remainder of 780.
The next digit of our result is 1. 
Result so far: 55980.10121
Subtract 820 from 1600 to get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

On to step 14:
820 goes into 7800 9 times with a remainder of 420.
Use 9 as the next digit of our solution. 
Result so far: 55980.101219
Subtracting 7380 from 7800 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 15:
4200 divided by 820 is 5 with a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 55980.1012195
The remainder is 100 after subtracting 4100 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 16:
If we divide 1000 by 820, we get 1 and a remainder of 180.
Put 1 as the next digit of the answer. 
Result so far: 55980.10121951
Subtracting 820 from 1000 leaves us 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.

After the division, we end up with 55980.10121951 and a remainder of 1.8e-07.
