1845804 ÷ 646 
We want to figure out the number of times 1845804 can be divided by 646.

Moving on to step 1:
646 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 646

Advancing to step 2:
If we divide 18 by 646, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 646

Going ahead to step 3:
When dividing 184 by 646, we get 0 with a remainder of 184.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 184 after subtracting 0 from 184.
Grab the next digit (5) from the dividend, add it to 184, then carry on: 1845 / 646

On to step 4:
1845 divided by 646 is 2 with a remainder of 553.
The next digit of our result is 2. 
Result so far: 2.0
If we take 1292 away from 1845, we end up with 553.
Include the next digit (8) from the dividend after 553, then repeat: 5538 / 646

Going ahead to step 5:
If we divide 5538 by 646, we get 8 and a remainder of 370.
Put 8 as the next digit of the answer. 
Result so far: 28.0
The remainder is 370 after subtracting 5168 from 5538.
Fetch the next digit (0) from the dividend, attach it to 370 and continue: 3700 / 646

Going ahead to step 6:
646 can be fit into 3700 5 times, resulting in a remainder of 470.
Record the quotient 5 as the next digit in the result. 
Result so far: 285.0
The remainder is 470 after subtracting 3230 from 3700.
Grab the next digit (4) from the dividend, add it to 470, then carry on: 4704 / 646

On to step 7:
4704 divided by 646 is 7 with a remainder of 182.
Record the quotient 7 as the next digit in the result. 
Result so far: 2857.0
If we subtract 4522 from 4704, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 8:
If we divide 1820 by 646, we get 2 and a remainder of 528.
Use 2 as the next digit of our solution. 
Result so far: 2857.2
Subtracting 1292 from 1820 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Advancing to step 9:
The number 646 fits into 5280 8 times, leaving a remainder of 112.
Use 8 as the next digit of our solution. 
Result so far: 2857.28
Subtract 5168 from 5280 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 10:
646 goes into 1120 1 times with a remainder of 474.
The next digit of our result is 1. 
Result so far: 2857.281
Deduct 646 from 1120 and we're left with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Step 11:
4740 divided by 646 is 7 with a remainder of 218.
Put 7 as the next digit of the answer. 
Result so far: 2857.2817
Deduct 4522 from 4740 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Moving on to step 12:
646 can be fit into 2180 3 times, resulting in a remainder of 242.
Write down 3 as next digit of the result. 
Result so far: 2857.28173
Subtracting 1938 from 2180 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Advancing to step 13:
When dividing 2420 by 646, we get 3 with a remainder of 482.
Record the quotient 3 as the next digit in the result. 
Result so far: 2857.281733
If we take 1938 away from 2420, we end up with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

The quotient of the division is 2857.281733, and the remainder is 4.82e-05.
