We divide 72129591 by 945
We want to figure out the number of times 72129591 can be divided by 945.

Going ahead to step 1:
7 divided by 945 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 945

Let's proceed to step 2:
When dividing 72 by 945, we get 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 945

Going ahead to step 3:
The number 945 fits into 721 0 times, leaving a remainder of 721.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 721 to get 721.
Bring next digit (2) of the dividend behind the 721 and repeat the process: 7212 / 945

Let's proceed to step 4:
The number 945 fits into 7212 7 times, leaving a remainder of 597.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 6615 from 7212 leaves us with 597.
Append the next digit (9) from the dividend to 597 and continue with: 5979 / 945

Moving on to step 5:
945 goes into 5979 6 times with a remainder of 309.
Put 6 as the next digit of the answer. 
Result so far: 76.0
If we subtract 5670 from 5979, we get 309.
Bring next digit (5) of the dividend behind the 309 and repeat the process: 3095 / 945

Going ahead to step 6:
945 goes into 3095 3 times with a remainder of 260.
Write down 3 as next digit of the result. 
Result so far: 763.0
If we take 2835 away from 3095, we end up with 260.
Fetch the next digit (9) from the dividend, attach it to 260 and continue: 2609 / 945

Advancing to step 7:
2609 divided by 945 is 2 with a remainder of 719.
The number 2 becomes the next digit in our result. 
Result so far: 7632.0
If we subtract 1890 from 2609, we get 719.
Append the next digit (1) from the dividend to 719 and continue with: 7191 / 945

Going ahead to step 8:
945 can be fit into 7191 7 times, resulting in a remainder of 576.
The next digit of our result is 7. 
Result so far: 76327.0
Deduct 6615 from 7191 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 9:
When dividing 5760 by 945, we get 6 with a remainder of 90.
Use 6 as the next digit of our solution. 
Result so far: 76327.6
The remainder is 90 after subtracting 5670 from 5760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
If we divide 900 by 945, we get 0 and a remainder of 900.
Use 0 as the next digit of our solution. 
Result so far: 76327.6
Subtracting 0 from 900 leaves us with 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Going ahead to step 11:
9000 divided by 945 is 9 with a remainder of 495.
Use 9 as the next digit of our solution. 
Result so far: 76327.609
Subtract 8505 from 9000 to get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Going ahead to step 12:
4950 divided by 945 is 5 with a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 76327.6095
If we subtract 4725 from 4950, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 13:
When dividing 2250 by 945, we get 2 with a remainder of 360.
The number 2 becomes the next digit in our result. 
Result so far: 76327.60952
Subtract 1890 from 2250 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 14:
945 can be fit into 3600 3 times, resulting in a remainder of 765.
Put 3 as the next digit of the answer. 
Result so far: 76327.609523
If we subtract 2835 from 3600, we get 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

On to step 15:
7650 divided by 945 is 8 with a remainder of 90.
Use 8 as the next digit of our solution. 
Result so far: 76327.6095238
The remainder is 90 after subtracting 7560 from 7650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 16:
If we divide 900 by 945, we get 0 and a remainder of 900.
Write down 0 as next digit of the result. 
Result so far: 76327.6095238
Subtracting 0 from 900 leaves us with 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Our division results in 76327.6095238 with a remaining 9e-07.
