Let's divide 217142 by 91
Our goal is to divide 217142 by 91.

Advancing to step 1:
91 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 91

Advancing to step 2:
The number 91 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 91

Advancing to step 3:
When dividing 217 by 91, we get 2 with a remainder of 35.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 182 away from 217, we end up with 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 91

Going ahead to step 4:
91 goes into 351 3 times with a remainder of 78.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we subtract 273 from 351, we get 78.
Bring next digit (4) of the dividend behind the 78 and repeat the process: 784 / 91

Let's proceed to step 5:
784 divided by 91 is 8 with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 238.0
Subtracting 728 from 784 leaves us with 56.
Append the next digit (2) from the dividend to 56 and continue with: 562 / 91

Let's proceed to step 6:
91 can be fit into 562 6 times, resulting in a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 2386.0
The remainder is 16 after subtracting 546 from 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
160 divided by 91 is 1 with a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 2386.1
If we take 91 away from 160, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 8:
91 goes into 690 7 times with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 2386.17
The remainder is 53 after subtracting 637 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 9:
The number 91 fits into 530 5 times, leaving a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 2386.175
Deduct 455 from 530 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 10:
If we divide 750 by 91, we get 8 and a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 2386.1758
If we subtract 728 from 750, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
91 goes into 220 2 times with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 2386.17582
Subtracting 182 from 220 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
91 goes into 380 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 2386.175824
Subtract 364 from 380 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
91 goes into 160 1 times with a remainder of 69.
The next digit of our result is 1. 
Result so far: 2386.1758241
Subtracting 91 from 160 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 14:
The number 91 fits into 690 7 times, leaving a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 2386.17582417
If we take 637 away from 690, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

After the division, we end up with 2386.17582417 and a remainder of 5.3e-08.
