71653766 ÷ 645 
Let's see how many times 645 fits into 71653766.

Let's proceed to step 1:
When dividing 7 by 645, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 645

Going ahead to step 2:
71 divided by 645 is 0 with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Grab the next digit (6) from the dividend, add it to 71, then carry on: 716 / 645

On to step 3:
When dividing 716 by 645, we get 1 with a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 645 from 716 to get 71.
Grab the next digit (5) from the dividend, add it to 71, then carry on: 715 / 645

Step 4:
715 divided by 645 is 1 with a remainder of 70.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 645 from 715 and we're left with 70.
Bring next digit (3) of the dividend behind the 70 and repeat the process: 703 / 645

Let's proceed to step 5:
The number 645 fits into 703 1 times, leaving a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
The remainder is 58 after subtracting 645 from 703.
Grab the next digit (7) from the dividend, add it to 58, then carry on: 587 / 645

Moving on to step 6:
645 goes into 587 0 times with a remainder of 587.
Record the quotient 0 as the next digit in the result. 
Result so far: 1110.0
If we take 0 away from 587, we end up with 587.
Bring next digit (6) of the dividend behind the 587 and repeat the process: 5876 / 645

Let's proceed to step 7:
When dividing 5876 by 645, we get 9 with a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 11109.0
Subtracting 5805 from 5876 leaves us with 71.
Bring next digit (6) of the dividend behind the 71 and repeat the process: 716 / 645

Going ahead to step 8:
When dividing 716 by 645, we get 1 with a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 111091.0
Deduct 645 from 716 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 9:
645 goes into 710 1 times with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 111091.1
If we take 645 away from 710, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 10:
645 goes into 650 1 times with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 111091.11
The remainder is 5 after subtracting 645 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 111091.11 with a remainder of 0.005.
