We look at the division of 81191687 by 428 
We're looking to find how many times 428 goes into 81191687.

Step 1:
428 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 428

Going ahead to step 2:
When dividing 81 by 428, we get 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Append the next digit (1) from the dividend to 81 and continue with: 811 / 428

Let's proceed to step 3:
811 divided by 428 is 1 with a remainder of 383.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 428 away from 811, we end up with 383.
Take the next digit (9) from the dividend and append it to 383, then repeat: 3839 / 428

Advancing to step 4:
428 can be fit into 3839 8 times, resulting in a remainder of 415.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 3424 from 3839 to get 415.
Fetch the next digit (1) from the dividend, attach it to 415 and continue: 4151 / 428

Going ahead to step 5:
428 goes into 4151 9 times with a remainder of 299.
Write down 9 as next digit of the result. 
Result so far: 189.0
If we subtract 3852 from 4151, we get 299.
Append the next digit (6) from the dividend to 299 and continue with: 2996 / 428

Let's proceed to step 6:
The number 428 fits into 2996 7 times, leaving a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 1897.0
The remainder is 0 after subtracting 2996 from 2996.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 428

On to step 7:
If we divide 8 by 428, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 18970.0
Subtract 0 from 8 to get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 428

On to step 8:
87 divided by 428 is 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 189700.0
If we take 0 away from 87, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 9:
428 can be fit into 870 2 times, resulting in a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 189700.2
If we take 856 away from 870, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
When dividing 140 by 428, we get 0 with a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 189700.2
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
428 can be fit into 1400 3 times, resulting in a remainder of 116.
Record the quotient 3 as the next digit in the result. 
Result so far: 189700.203
If we subtract 1284 from 1400, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 12:
428 goes into 1160 2 times with a remainder of 304.
The number 2 becomes the next digit in our result. 
Result so far: 189700.2032
If we take 856 away from 1160, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 13:
428 goes into 3040 7 times with a remainder of 44.
Write down 7 as next digit of the result. 
Result so far: 189700.20327
If we subtract 2996 from 3040, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
440 divided by 428 is 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 189700.203271
If we subtract 428 from 440, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 15:
When dividing 120 by 428, we get 0 with a remainder of 120.
The next digit of our result is 0. 
Result so far: 189700.203271
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 16:
428 goes into 1200 2 times with a remainder of 344.
Record the quotient 2 as the next digit in the result. 
Result so far: 189700.20327102
Subtract 856 from 1200 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

After the division, we end up with 189700.20327102 and a remainder of 3.44e-07.
