We're dividing 62687719 by 645 
We want to figure out the number of times 62687719 can be divided by 645.

Moving on to step 1:
645 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 645

On to step 2:
62 divided by 645 is 0 with a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 62, we get 62.
Take the next digit (6) from the dividend and append it to 62, then repeat: 626 / 645

On to step 3:
645 can be fit into 626 0 times, resulting in a remainder of 626.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 626 and we're left with 626.
Append the next digit (8) from the dividend to 626 and continue with: 6268 / 645

Let's proceed to step 4:
645 can be fit into 6268 9 times, resulting in a remainder of 463.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 5805 away from 6268, we end up with 463.
Take the next digit (7) from the dividend and append it to 463, then repeat: 4637 / 645

Going ahead to step 5:
The number 645 fits into 4637 7 times, leaving a remainder of 122.
Use 7 as the next digit of our solution. 
Result so far: 97.0
If we subtract 4515 from 4637, we get 122.
Take the next digit (7) from the dividend and append it to 122, then repeat: 1227 / 645

Let's proceed to step 6:
1227 divided by 645 is 1 with a remainder of 582.
Write down 1 as next digit of the result. 
Result so far: 971.0
If we subtract 645 from 1227, we get 582.
Include the next digit (1) from the dividend after 582, then repeat: 5821 / 645

On to step 7:
When dividing 5821 by 645, we get 9 with a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 9719.0
Subtracting 5805 from 5821 leaves us with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 645

Advancing to step 8:
The number 645 fits into 169 0 times, leaving a remainder of 169.
Write down 0 as next digit of the result. 
Result so far: 97190.0
If we subtract 0 from 169, we get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Moving on to step 9:
When dividing 1690 by 645, we get 2 with a remainder of 400.
Use 2 as the next digit of our solution. 
Result so far: 97190.2
The remainder is 400 after subtracting 1290 from 1690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 10:
645 can be fit into 4000 6 times, resulting in a remainder of 130.
Use 6 as the next digit of our solution. 
Result so far: 97190.26
If we subtract 3870 from 4000, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 11:
If we divide 1300 by 645, we get 2 and a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 97190.262
If we take 1290 away from 1300, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
When dividing 100 by 645, we get 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 97190.262
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 13:
If we divide 1000 by 645, we get 1 and a remainder of 355.
Record the quotient 1 as the next digit in the result. 
Result so far: 97190.26201
Subtract 645 from 1000 to get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Moving on to step 14:
645 goes into 3550 5 times with a remainder of 325.
The number 5 becomes the next digit in our result. 
Result so far: 97190.262015
Subtracting 3225 from 3550 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Let's proceed to step 15:
645 can be fit into 3250 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 97190.2620155
Deduct 3225 from 3250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 97190.2620155, with a leftover of 2.5e-07.
