We look at the division of 429021 by 91 
We want to divide 429021 by 91.

Step 1:
4 divided by 91 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 91

Let's proceed to step 2:
91 can be fit into 42 0 times, resulting in a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Take the next digit (9) from the dividend and append it to 42, then repeat: 429 / 91

Going ahead to step 3:
429 divided by 91 is 4 with a remainder of 65.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 364 from 429, we get 65.
Bring next digit (0) of the dividend behind the 65 and repeat the process: 650 / 91

Step 4:
650 divided by 91 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we take 637 away from 650, we end up with 13.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 91

Advancing to step 5:
91 can be fit into 132 1 times, resulting in a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 471.0
Subtract 91 from 132 to get 41.
Append the next digit (1) from the dividend to 41 and continue with: 411 / 91

Going ahead to step 6:
The number 91 fits into 411 4 times, leaving a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 4714.0
If we subtract 364 from 411, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 7:
When dividing 470 by 91, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 4714.5
If we take 455 away from 470, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
When dividing 150 by 91, we get 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 4714.51
The remainder is 59 after subtracting 91 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 9:
91 goes into 590 6 times with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 4714.516
Subtracting 546 from 590 leaves us with 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 10:
If we divide 440 by 91, we get 4 and a remainder of 76.
The next digit of our result is 4. 
Result so far: 4714.5164
Deduct 364 from 440 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 11:
91 can be fit into 760 8 times, resulting in a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 4714.51648
Deduct 728 from 760 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
91 can be fit into 320 3 times, resulting in a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 4714.516483
If we subtract 273 from 320, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 13:
When dividing 470 by 91, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 4714.5164835
If we take 455 away from 470, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
When dividing 150 by 91, we get 1 with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 4714.51648351
Subtracting 91 from 150 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Our division results in 4714.51648351 with a remaining 5.9e-08.
