Let's divide 71638677 by 428
We want to figure out the number of times 71638677 can be divided by 428.

Step 1:
The number 428 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 428

Advancing to step 2:
71 divided by 428 is 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Bring next digit (6) of the dividend behind the 71 and repeat the process: 716 / 428

Let's proceed to step 3:
428 can be fit into 716 1 times, resulting in a remainder of 288.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 428 from 716 and we're left with 288.
Take the next digit (3) from the dividend and append it to 288, then repeat: 2883 / 428

Going ahead to step 4:
428 goes into 2883 6 times with a remainder of 315.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 2568 from 2883 leaves us with 315.
Fetch the next digit (8) from the dividend, attach it to 315 and continue: 3158 / 428

Moving on to step 5:
428 goes into 3158 7 times with a remainder of 162.
Write down 7 as next digit of the result. 
Result so far: 167.0
The remainder is 162 after subtracting 2996 from 3158.
Append the next digit (6) from the dividend to 162 and continue with: 1626 / 428

Let's proceed to step 6:
428 goes into 1626 3 times with a remainder of 342.
The next digit of our result is 3. 
Result so far: 1673.0
Deduct 1284 from 1626 and we're left with 342.
Append the next digit (7) from the dividend to 342 and continue with: 3427 / 428

On to step 7:
428 can be fit into 3427 8 times, resulting in a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 16738.0
If we take 3424 away from 3427, we end up with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 428

Step 8:
The number 428 fits into 37 0 times, leaving a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 167380.0
The remainder is 37 after subtracting 0 from 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 9:
428 can be fit into 370 0 times, resulting in a remainder of 370.
Use 0 as the next digit of our solution. 
Result so far: 167380.0
Subtract 0 from 370 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 10:
428 can be fit into 3700 8 times, resulting in a remainder of 276.
Use 8 as the next digit of our solution. 
Result so far: 167380.08
The remainder is 276 after subtracting 3424 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 11:
2760 divided by 428 is 6 with a remainder of 192.
Record the quotient 6 as the next digit in the result. 
Result so far: 167380.086
If we subtract 2568 from 2760, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 12:
428 can be fit into 1920 4 times, resulting in a remainder of 208.
The number 4 becomes the next digit in our result. 
Result so far: 167380.0864
If we subtract 1712 from 1920, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 13:
428 goes into 2080 4 times with a remainder of 368.
The number 4 becomes the next digit in our result. 
Result so far: 167380.08644
If we subtract 1712 from 2080, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The final result is 167380.08644 with a remainder of 0.000368.
