We divide 420577 by 91
We want to divide 420577 by 91.

Moving on to step 1:
91 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 91

Going ahead to step 2:
91 goes into 42 0 times with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 91

Step 3:
If we divide 420 by 91, we get 4 and a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 364 from 420 and we're left with 56.
Bring next digit (5) of the dividend behind the 56 and repeat the process: 565 / 91

Moving on to step 4:
565 divided by 91 is 6 with a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 46.0
If we take 546 away from 565, we end up with 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 91

On to step 5:
197 divided by 91 is 2 with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 462.0
Subtracting 182 from 197 leaves us with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 91

Let's proceed to step 6:
157 divided by 91 is 1 with a remainder of 66.
The number 1 becomes the next digit in our result. 
Result so far: 4621.0
Subtract 91 from 157 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 7:
91 goes into 660 7 times with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 4621.7
If we take 637 away from 660, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 8:
230 divided by 91 is 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 4621.72
Subtract 182 from 230 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
480 divided by 91 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 4621.725
The remainder is 25 after subtracting 455 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 10:
250 divided by 91 is 2 with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 4621.7252
Subtracting 182 from 250 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 11:
91 goes into 680 7 times with a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 4621.72527
The remainder is 43 after subtracting 637 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 12:
When dividing 430 by 91, we get 4 with a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 4621.725274
The remainder is 66 after subtracting 364 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 13:
91 goes into 660 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 4621.7252747
Subtracting 637 from 660 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 14:
91 goes into 230 2 times with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 4621.72527472
Subtract 182 from 230 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 4621.72527472, and the remainder is 4.8e-08.
