We're dividing 91428070 by 28 
We want to divide 91428070 by 28.

Moving on to step 1:
28 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 28

Advancing to step 2:
28 can be fit into 91 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 84 from 91 and we're left with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 28

Let's proceed to step 3:
If we divide 74 by 28, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we subtract 56 from 74, we get 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 28

Moving on to step 4:
When dividing 182 by 28, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 326.0
Deduct 168 from 182 and we're left with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 28

Let's proceed to step 5:
28 goes into 148 5 times with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 3265.0
Subtract 140 from 148 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 28

On to step 6:
If we divide 80 by 28, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 32652.0
The remainder is 24 after subtracting 56 from 80.
Bring next digit (7) of the dividend behind the 24 and repeat the process: 247 / 28

Moving on to step 7:
247 divided by 28 is 8 with a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 326528.0
If we take 224 away from 247, we end up with 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 28

Moving on to step 8:
28 can be fit into 230 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 3265288.0
Deduct 224 from 230 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
When dividing 60 by 28, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 3265288.2
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
The number 28 fits into 40 1 times, leaving a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 3265288.21
Deduct 28 from 40 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 3265288.214
If we take 112 away from 120, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
The number 28 fits into 80 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 3265288.2142
Deduct 56 from 80 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3265288.21428
If we take 224 away from 240, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
When dividing 160 by 28, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 3265288.214285
If we subtract 140 from 160, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 15:
If we divide 200 by 28, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 3265288.2142857
If we take 196 away from 200, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 16:
28 goes into 40 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 3265288.21428571
Subtract 28 from 40 to 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.

After the division, we end up with 3265288.21428571 and a remainder of 1.2e-08.
