We look at the division of 76622985 by 645 
We want to divide 76622985 by 645.

Going ahead to step 1:
If we divide 7 by 645, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 645

Let's proceed to step 2:
When dividing 76 by 645, we get 0 with a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Grab the next digit (6) from the dividend, add it to 76, then carry on: 766 / 645

Step 3:
645 goes into 766 1 times with a remainder of 121.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 121 after subtracting 645 from 766.
Append the next digit (2) from the dividend to 121 and continue with: 1212 / 645

Let's proceed to step 4:
The number 645 fits into 1212 1 times, leaving a remainder of 567.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 645 from 1212 to get 567.
Include the next digit (2) from the dividend after 567, then repeat: 5672 / 645

On to step 5:
The number 645 fits into 5672 8 times, leaving a remainder of 512.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
If we take 5160 away from 5672, we end up with 512.
Fetch the next digit (9) from the dividend, attach it to 512 and continue: 5129 / 645

Step 6:
If we divide 5129 by 645, we get 7 and a remainder of 614.
Record the quotient 7 as the next digit in the result. 
Result so far: 1187.0
Subtracting 4515 from 5129 leaves us with 614.
Fetch the next digit (8) from the dividend, attach it to 614 and continue: 6148 / 645

Moving on to step 7:
When dividing 6148 by 645, we get 9 with a remainder of 343.
Use 9 as the next digit of our solution. 
Result so far: 11879.0
Subtracting 5805 from 6148 leaves us with 343.
Include the next digit (5) from the dividend after 343, then repeat: 3435 / 645

Step 8:
When dividing 3435 by 645, we get 5 with a remainder of 210.
Write down 5 as next digit of the result. 
Result so far: 118795.0
The remainder is 210 after subtracting 3225 from 3435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 9:
645 goes into 2100 3 times with a remainder of 165.
The number 3 becomes the next digit in our result. 
Result so far: 118795.3
Deduct 1935 from 2100 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 10:
The number 645 fits into 1650 2 times, leaving a remainder of 360.
Write down 2 as next digit of the result. 
Result so far: 118795.32
If we take 1290 away from 1650, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 11:
3600 divided by 645 is 5 with a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 118795.325
The remainder is 375 after subtracting 3225 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Going ahead to step 12:
645 can be fit into 3750 5 times, resulting in a remainder of 525.
Put 5 as the next digit of the answer. 
Result so far: 118795.3255
Subtracting 3225 from 3750 leaves us with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

The final outcome is 118795.3255, with a leftover of 0.00525.
