Let's divide 645591 by 76
We want to figure out the number of times 645591 can be divided by 76.

On to step 1:
76 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 76

Moving on to step 2:
When dividing 64 by 76, we get 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Append the next digit (5) from the dividend to 64 and continue with: 645 / 76

Moving on to step 3:
The number 76 fits into 645 8 times, leaving a remainder of 37.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 37 after subtracting 608 from 645.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 76

Going ahead to step 4:
76 can be fit into 375 4 times, resulting in a remainder of 71.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
Subtracting 304 from 375 leaves us with 71.
Grab the next digit (9) from the dividend, add it to 71, then carry on: 719 / 76

Let's proceed to step 5:
76 goes into 719 9 times with a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 849.0
Deduct 684 from 719 and we're left with 35.
Append the next digit (1) from the dividend to 35 and continue with: 351 / 76

Advancing to step 6:
351 divided by 76 is 4 with a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 8494.0
Deduct 304 from 351 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 7:
When dividing 470 by 76, we get 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 8494.6
Subtracting 456 from 470 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
The number 76 fits into 140 1 times, leaving a remainder of 64.
The next digit of our result is 1. 
Result so far: 8494.61
If we take 76 away from 140, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
76 goes into 640 8 times with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 8494.618
Subtract 608 from 640 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
320 divided by 76 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 8494.6184
The remainder is 16 after subtracting 304 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
When dividing 160 by 76, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 8494.61842
Deduct 152 from 160 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
When dividing 80 by 76, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 8494.618421
If we subtract 76 from 80, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
The number 76 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 8494.618421
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
76 goes into 400 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 8494.61842105
If we take 380 away from 400, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 8494.61842105 and a remainder of 2e-08.
