102128 ÷ 91 
We want to divide 102128 by 91.

Let's proceed to step 1:
91 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 91

Advancing to step 2:
10 divided by 91 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 91

Let's proceed to step 3:
If we divide 102 by 91, we get 1 and a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
If we take 91 away from 102, we end up with 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 91

Let's proceed to step 4:
If we divide 111 by 91, we get 1 and a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 91 away from 111, we end up with 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 91

Step 5:
If we divide 202 by 91, we get 2 and a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 112.0
Deduct 182 from 202 and we're left with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 91

Moving on to step 6:
When dividing 208 by 91, we get 2 with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 1122.0
If we subtract 182 from 208, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
The number 91 fits into 260 2 times, leaving a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 1122.2
The remainder is 78 after subtracting 182 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 8:
When dividing 780 by 91, we get 8 with a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 1122.28
If we subtract 728 from 780, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 9:
91 goes into 520 5 times with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 1122.285
The remainder is 65 after subtracting 455 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 10:
91 goes into 650 7 times with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 1122.2857
Subtract 637 from 650 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
If we divide 130 by 91, we get 1 and a remainder of 39.
The next digit of our result is 1. 
Result so far: 1122.28571
Subtracting 91 from 130 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 12:
91 can be fit into 390 4 times, resulting in a remainder of 26.
The next digit of our result is 4. 
Result so far: 1122.285714
If we subtract 364 from 390, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
91 goes into 260 2 times with a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 1122.2857142
Subtract 182 from 260 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 14:
91 goes into 780 8 times with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 1122.28571428
Subtracting 728 from 780 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 1122.28571428 and a remainder of 5.2e-08.
