We look at the division of 457426 by 89 
We want to figure out the number of times 457426 can be divided by 89.

Going ahead to step 1:
If we divide 4 by 89, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 89

Going ahead to step 2:
When dividing 45 by 89, we get 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Take the next digit (7) from the dividend and append it to 45, then repeat: 457 / 89

Step 3:
If we divide 457 by 89, we get 5 and a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 445 from 457, we get 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 89

Let's proceed to step 4:
When dividing 124 by 89, we get 1 with a remainder of 35.
The next digit of our result is 1. 
Result so far: 51.0
Subtracting 89 from 124 leaves us with 35.
Append the next digit (2) from the dividend to 35 and continue with: 352 / 89

Advancing to step 5:
If we divide 352 by 89, we get 3 and a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 513.0
Subtract 267 from 352 to get 85.
Fetch the next digit (6) from the dividend, attach it to 85 and continue: 856 / 89

Advancing to step 6:
856 divided by 89 is 9 with a remainder of 55.
The number 9 becomes the next digit in our result. 
Result so far: 5139.0
Subtract 801 from 856 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 7:
If we divide 550 by 89, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 5139.6
Deduct 534 from 550 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
89 goes into 160 1 times with a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 5139.61
If we subtract 89 from 160, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 9:
89 goes into 710 7 times with a remainder of 87.
The next digit of our result is 7. 
Result so far: 5139.617
If we take 623 away from 710, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 10:
870 divided by 89 is 9 with a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 5139.6179
The remainder is 69 after subtracting 801 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 11:
690 divided by 89 is 7 with a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 5139.61797
Subtract 623 from 690 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 12:
670 divided by 89 is 7 with a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 5139.617977
Deduct 623 from 670 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final outcome is 5139.617977, with a leftover of 4.7e-06.
