We look at the division of 27750062 by 645 
We're looking to find how many times 645 goes into 27750062.

Step 1:
645 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 645

Going ahead to step 2:
The number 645 fits into 27 0 times, leaving a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Bring next digit (7) of the dividend behind the 27 and repeat the process: 277 / 645

Step 3:
If we divide 277 by 645, we get 0 and a remainder of 277.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 277 and we're left with 277.
Append the next digit (5) from the dividend to 277 and continue with: 2775 / 645

Step 4:
The number 645 fits into 2775 4 times, leaving a remainder of 195.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 2580 from 2775 to get 195.
Append the next digit (0) from the dividend to 195 and continue with: 1950 / 645

Going ahead to step 5:
When dividing 1950 by 645, we get 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Deduct 1935 from 1950 and we're left with 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 645

Step 6:
645 goes into 150 0 times with a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 430.0
Deduct 0 from 150 and we're left with 150.
Bring next digit (6) of the dividend behind the 150 and repeat the process: 1506 / 645

Going ahead to step 7:
645 goes into 1506 2 times with a remainder of 216.
Use 2 as the next digit of our solution. 
Result so far: 4302.0
Deduct 1290 from 1506 and we're left with 216.
Grab the next digit (2) from the dividend, add it to 216, then carry on: 2162 / 645

Advancing to step 8:
If we divide 2162 by 645, we get 3 and a remainder of 227.
Record the quotient 3 as the next digit in the result. 
Result so far: 43023.0
If we subtract 1935 from 2162, we get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Let's proceed to step 9:
The number 645 fits into 2270 3 times, leaving a remainder of 335.
Put 3 as the next digit of the answer. 
Result so far: 43023.3
Subtract 1935 from 2270 to get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Moving on to step 10:
645 goes into 3350 5 times with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 43023.35
The remainder is 125 after subtracting 3225 from 3350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 11:
1250 divided by 645 is 1 with a remainder of 605.
Write down 1 as next digit of the result. 
Result so far: 43023.351
If we take 645 away from 1250, we end up with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Moving on to step 12:
645 can be fit into 6050 9 times, resulting in a remainder of 245.
Use 9 as the next digit of our solution. 
Result so far: 43023.3519
Deduct 5805 from 6050 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 13:
2450 divided by 645 is 3 with a remainder of 515.
Use 3 as the next digit of our solution. 
Result so far: 43023.35193
If we take 1935 away from 2450, we end up with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Let's proceed to step 14:
If we divide 5150 by 645, we get 7 and a remainder of 635.
Write down 7 as next digit of the result. 
Result so far: 43023.351937
Subtracting 4515 from 5150 leaves us with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Moving on to step 15:
645 can be fit into 6350 9 times, resulting in a remainder of 545.
Write down 9 as next digit of the result. 
Result so far: 43023.3519379
Subtracting 5805 from 6350 leaves us with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Moving on to step 16:
5450 divided by 645 is 8 with a remainder of 290.
Write down 8 as next digit of the result. 
Result so far: 43023.35193798
The remainder is 290 after subtracting 5160 from 5450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

The final outcome is 43023.35193798, with a leftover of 2.9e-07.
