Let's divide 67887990 by 945
We want to figure out the number of times 67887990 can be divided by 945.

Step 1:
When dividing 6 by 945, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 945

Step 2:
If we divide 67 by 945, we get 0 and a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Fetch the next digit (8) from the dividend, attach it to 67 and continue: 678 / 945

Advancing to step 3:
If we divide 678 by 945, we get 0 and a remainder of 678.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 678, we get 678.
Grab the next digit (8) from the dividend, add it to 678, then carry on: 6788 / 945

Let's proceed to step 4:
When dividing 6788 by 945, we get 7 with a remainder of 173.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 173 after subtracting 6615 from 6788.
Fetch the next digit (7) from the dividend, attach it to 173 and continue: 1737 / 945

Step 5:
The number 945 fits into 1737 1 times, leaving a remainder of 792.
Use 1 as the next digit of our solution. 
Result so far: 71.0
The remainder is 792 after subtracting 945 from 1737.
Grab the next digit (9) from the dividend, add it to 792, then carry on: 7929 / 945

On to step 6:
The number 945 fits into 7929 8 times, leaving a remainder of 369.
The number 8 becomes the next digit in our result. 
Result so far: 718.0
Deduct 7560 from 7929 and we're left with 369.
Bring next digit (9) of the dividend behind the 369 and repeat the process: 3699 / 945

Advancing to step 7:
945 can be fit into 3699 3 times, resulting in a remainder of 864.
Record the quotient 3 as the next digit in the result. 
Result so far: 7183.0
If we subtract 2835 from 3699, we get 864.
Take the next digit (0) from the dividend and append it to 864, then repeat: 8640 / 945

Step 8:
If we divide 8640 by 945, we get 9 and a remainder of 135.
Write down 9 as next digit of the result. 
Result so far: 71839.0
Subtract 8505 from 8640 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 9:
1350 divided by 945 is 1 with a remainder of 405.
The next digit of our result is 1. 
Result so far: 71839.1
The remainder is 405 after subtracting 945 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Going ahead to step 10:
945 goes into 4050 4 times with a remainder of 270.
Use 4 as the next digit of our solution. 
Result so far: 71839.14
If we take 3780 away from 4050, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 11:
When dividing 2700 by 945, we get 2 with a remainder of 810.
Record the quotient 2 as the next digit in the result. 
Result so far: 71839.142
If we subtract 1890 from 2700, we get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

On to step 12:
8100 divided by 945 is 8 with a remainder of 540.
Write down 8 as next digit of the result. 
Result so far: 71839.1428
Subtract 7560 from 8100 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 13:
If we divide 5400 by 945, we get 5 and a remainder of 675.
Put 5 as the next digit of the answer. 
Result so far: 71839.14285
If we subtract 4725 from 5400, we get 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Going ahead to step 14:
If we divide 6750 by 945, we get 7 and a remainder of 135.
Use 7 as the next digit of our solution. 
Result so far: 71839.142857
If we subtract 6615 from 6750, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 15:
1350 divided by 945 is 1 with a remainder of 405.
Put 1 as the next digit of the answer. 
Result so far: 71839.1428571
If we take 945 away from 1350, we end up with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Step 16:
The number 945 fits into 4050 4 times, leaving a remainder of 270.
The next digit of our result is 4. 
Result so far: 71839.14285714
Subtracting 3780 from 4050 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

The quotient of the division is 71839.14285714, and the remainder is 2.7e-07.
