We look at the division of 71750697 by 643 
We want to figure out the number of times 71750697 can be divided by 643.

On to step 1:
When dividing 7 by 643, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 643

Advancing to step 2:
643 can be fit into 71 0 times, resulting in a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Bring next digit (7) of the dividend behind the 71 and repeat the process: 717 / 643

On to step 3:
The number 643 fits into 717 1 times, leaving a remainder of 74.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 643 from 717 to get 74.
Append the next digit (5) from the dividend to 74 and continue with: 745 / 643

Step 4:
When dividing 745 by 643, we get 1 with a remainder of 102.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 102 after subtracting 643 from 745.
Take the next digit (0) from the dividend and append it to 102, then repeat: 1020 / 643

Advancing to step 5:
1020 divided by 643 is 1 with a remainder of 377.
Use 1 as the next digit of our solution. 
Result so far: 111.0
Subtracting 643 from 1020 leaves us with 377.
Append the next digit (6) from the dividend to 377 and continue with: 3776 / 643

Let's proceed to step 6:
643 can be fit into 3776 5 times, resulting in a remainder of 561.
Use 5 as the next digit of our solution. 
Result so far: 1115.0
Deduct 3215 from 3776 and we're left with 561.
Include the next digit (9) from the dividend after 561, then repeat: 5619 / 643

On to step 7:
If we divide 5619 by 643, we get 8 and a remainder of 475.
Write down 8 as next digit of the result. 
Result so far: 11158.0
If we subtract 5144 from 5619, we get 475.
Fetch the next digit (7) from the dividend, attach it to 475 and continue: 4757 / 643

On to step 8:
When dividing 4757 by 643, we get 7 with a remainder of 256.
Use 7 as the next digit of our solution. 
Result so far: 111587.0
Subtract 4501 from 4757 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 9:
643 goes into 2560 3 times with a remainder of 631.
Use 3 as the next digit of our solution. 
Result so far: 111587.3
Deduct 1929 from 2560 and we're left with 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

Let's proceed to step 10:
The number 643 fits into 6310 9 times, leaving a remainder of 523.
Record the quotient 9 as the next digit in the result. 
Result so far: 111587.39
Deduct 5787 from 6310 and we're left with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Moving on to step 11:
If we divide 5230 by 643, we get 8 and a remainder of 86.
Record the quotient 8 as the next digit in the result. 
Result so far: 111587.398
If we subtract 5144 from 5230, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 12:
643 goes into 860 1 times with a remainder of 217.
The number 1 becomes the next digit in our result. 
Result so far: 111587.3981
Deduct 643 from 860 and we're left with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Advancing to step 13:
The number 643 fits into 2170 3 times, leaving a remainder of 241.
Write down 3 as next digit of the result. 
Result so far: 111587.39813
If we take 1929 away from 2170, we end up with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Moving on to step 14:
If we divide 2410 by 643, we get 3 and a remainder of 481.
Write down 3 as next digit of the result. 
Result so far: 111587.398133
Deduct 1929 from 2410 and we're left with 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

The final result is 111587.398133 with a remainder of 4.81e-05.
