47042552 divided by 645 
Let's see how many times 645 fits into 47042552.

Step 1:
645 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 645

Advancing to step 2:
645 goes into 47 0 times with a remainder of 47.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 47, we end up with 47.
Fetch the next digit (0) from the dividend, attach it to 47 and continue: 470 / 645

Let's proceed to step 3:
If we divide 470 by 645, we get 0 and a remainder of 470.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 470 leaves us with 470.
Append the next digit (4) from the dividend to 470 and continue with: 4704 / 645

Going ahead to step 4:
The number 645 fits into 4704 7 times, leaving a remainder of 189.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 4515 from 4704 and we're left with 189.
Bring next digit (2) of the dividend behind the 189 and repeat the process: 1892 / 645

On to step 5:
The number 645 fits into 1892 2 times, leaving a remainder of 602.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Subtracting 1290 from 1892 leaves us with 602.
Include the next digit (5) from the dividend after 602, then repeat: 6025 / 645

Going ahead to step 6:
645 can be fit into 6025 9 times, resulting in a remainder of 220.
The number 9 becomes the next digit in our result. 
Result so far: 729.0
If we take 5805 away from 6025, we end up with 220.
Take the next digit (5) from the dividend and append it to 220, then repeat: 2205 / 645

Let's proceed to step 7:
645 goes into 2205 3 times with a remainder of 270.
Use 3 as the next digit of our solution. 
Result so far: 7293.0
If we subtract 1935 from 2205, we get 270.
Append the next digit (2) from the dividend to 270 and continue with: 2702 / 645

Let's proceed to step 8:
The number 645 fits into 2702 4 times, leaving a remainder of 122.
Use 4 as the next digit of our solution. 
Result so far: 72934.0
Subtracting 2580 from 2702 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 9:
645 can be fit into 1220 1 times, resulting in a remainder of 575.
Record the quotient 1 as the next digit in the result. 
Result so far: 72934.1
If we take 645 away from 1220, we end up with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Advancing to step 10:
645 can be fit into 5750 8 times, resulting in a remainder of 590.
The next digit of our result is 8. 
Result so far: 72934.18
Subtract 5160 from 5750 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 11:
If we divide 5900 by 645, we get 9 and a remainder of 95.
The next digit of our result is 9. 
Result so far: 72934.189
If we subtract 5805 from 5900, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 12:
645 can be fit into 950 1 times, resulting in a remainder of 305.
Put 1 as the next digit of the answer. 
Result so far: 72934.1891
Subtracting 645 from 950 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 13:
3050 divided by 645 is 4 with a remainder of 470.
The number 4 becomes the next digit in our result. 
Result so far: 72934.18914
Deduct 2580 from 3050 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Moving on to step 14:
645 goes into 4700 7 times with a remainder of 185.
Put 7 as the next digit of the answer. 
Result so far: 72934.189147
Deduct 4515 from 4700 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 15:
645 can be fit into 1850 2 times, resulting in a remainder of 560.
Put 2 as the next digit of the answer. 
Result so far: 72934.1891472
Deduct 1290 from 1850 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 16:
645 goes into 5600 8 times with a remainder of 440.
Record the quotient 8 as the next digit in the result. 
Result so far: 72934.18914728
If we take 5160 away from 5600, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The final outcome is 72934.18914728, with a leftover of 4.4e-07.
