428211 ÷ 89 
We want to figure out the number of times 428211 can be divided by 89.

Moving on to step 1:
4 divided by 89 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 89

On to step 2:
If we divide 42 by 89, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 89

Advancing to step 3:
428 divided by 89 is 4 with a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 356 from 428 and we're left with 72.
Take the next digit (2) from the dividend and append it to 72, then repeat: 722 / 89

Step 4:
When dividing 722 by 89, we get 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Deduct 712 from 722 and we're left with 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 89

Step 5:
The number 89 fits into 101 1 times, leaving a remainder of 12.
The next digit of our result is 1. 
Result so far: 481.0
If we subtract 89 from 101, we get 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 89

Going ahead to step 6:
If we divide 121 by 89, we get 1 and a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 4811.0
Subtract 89 from 121 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
When dividing 320 by 89, we get 3 with a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 4811.3
If we take 267 away from 320, 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.

Let's proceed to step 8:
If we divide 530 by 89, we get 5 and a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 4811.35
Deduct 445 from 530 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 9:
89 goes into 850 9 times with a remainder of 49.
The next digit of our result is 9. 
Result so far: 4811.359
The remainder is 49 after subtracting 801 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 10:
490 divided by 89 is 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 4811.3595
Subtracting 445 from 490 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 11:
When dividing 450 by 89, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4811.35955
Subtract 445 from 450 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 4811.35955, with a leftover of 5e-06.
