47946241 divided by 645 
We want to figure out the number of times 47946241 can be divided by 645.

On to step 1:
If we divide 4 by 645, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 645

Let's proceed to step 2:
645 can be fit into 47 0 times, resulting in a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 47 and we're left with 47.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 645

Going ahead to step 3:
645 can be fit into 479 0 times, resulting in a remainder of 479.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 479 leaves us with 479.
Include the next digit (4) from the dividend after 479, then repeat: 4794 / 645

Moving on to step 4:
The number 645 fits into 4794 7 times, leaving a remainder of 279.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 4515 from 4794 leaves us with 279.
Include the next digit (6) from the dividend after 279, then repeat: 2796 / 645

On to step 5:
645 goes into 2796 4 times with a remainder of 216.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
The remainder is 216 after subtracting 2580 from 2796.
Include the next digit (2) from the dividend after 216, then repeat: 2162 / 645

Going ahead to step 6:
If we divide 2162 by 645, we get 3 and a remainder of 227.
Put 3 as the next digit of the answer. 
Result so far: 743.0
If we subtract 1935 from 2162, we get 227.
Grab the next digit (4) from the dividend, add it to 227, then carry on: 2274 / 645

Advancing to step 7:
The number 645 fits into 2274 3 times, leaving a remainder of 339.
Record the quotient 3 as the next digit in the result. 
Result so far: 7433.0
If we take 1935 away from 2274, we end up with 339.
Include the next digit (1) from the dividend after 339, then repeat: 3391 / 645

Let's proceed to step 8:
3391 divided by 645 is 5 with a remainder of 166.
Record the quotient 5 as the next digit in the result. 
Result so far: 74335.0
Deduct 3225 from 3391 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 9:
If we divide 1660 by 645, we get 2 and a remainder of 370.
Put 2 as the next digit of the answer. 
Result so far: 74335.2
The remainder is 370 after subtracting 1290 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 10:
If we divide 3700 by 645, we get 5 and a remainder of 475.
Write down 5 as next digit of the result. 
Result so far: 74335.25
If we take 3225 away from 3700, we end up with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Let's proceed to step 11:
645 can be fit into 4750 7 times, resulting in a remainder of 235.
Use 7 as the next digit of our solution. 
Result so far: 74335.257
If we take 4515 away from 4750, we end up with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

On to step 12:
If we divide 2350 by 645, we get 3 and a remainder of 415.
Record the quotient 3 as the next digit in the result. 
Result so far: 74335.2573
If we take 1935 away from 2350, we end up with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Step 13:
645 goes into 4150 6 times with a remainder of 280.
The number 6 becomes the next digit in our result. 
Result so far: 74335.25736
If we take 3870 away from 4150, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 14:
When dividing 2800 by 645, we get 4 with a remainder of 220.
Put 4 as the next digit of the answer. 
Result so far: 74335.257364
Deduct 2580 from 2800 and we're left 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.

Advancing to step 15:
The number 645 fits into 2200 3 times, leaving a remainder of 265.
Put 3 as the next digit of the answer. 
Result so far: 74335.2573643
Subtract 1935 from 2200 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 16:
The number 645 fits into 2650 4 times, leaving a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 74335.25736434
If we take 2580 away from 2650, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 74335.25736434, with a leftover of 7e-08.
