350401 ÷ 89 
Our goal is to divide 350401 by 89.

Step 1:
3 divided by 89 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 89

Advancing to step 2:
When dividing 35 by 89, we get 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Append the next digit (0) from the dividend to 35 and continue with: 350 / 89

On to step 3:
If we divide 350 by 89, we get 3 and a remainder of 83.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 267 from 350 to get 83.
Append the next digit (4) from the dividend to 83 and continue with: 834 / 89

On to step 4:
89 goes into 834 9 times with a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 39.0
The remainder is 33 after subtracting 801 from 834.
Fetch the next digit (0) from the dividend, attach it to 33 and continue: 330 / 89

Step 5:
89 goes into 330 3 times with a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 393.0
If we subtract 267 from 330, we get 63.
Append the next digit (1) from the dividend to 63 and continue with: 631 / 89

Going ahead to step 6:
The number 89 fits into 631 7 times, leaving a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 3937.0
If we subtract 623 from 631, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
89 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 3937.0
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 8:
89 can be fit into 800 8 times, resulting in a remainder of 88.
The next digit of our result is 8. 
Result so far: 3937.08
Subtract 712 from 800 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 9:
89 can be fit into 880 9 times, resulting in a remainder of 79.
The number 9 becomes the next digit in our result. 
Result so far: 3937.089
The remainder is 79 after subtracting 801 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 10:
89 goes into 790 8 times with a remainder of 78.
The next digit of our result is 8. 
Result so far: 3937.0898
Subtracting 712 from 790 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 11:
780 divided by 89 is 8 with a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 3937.08988
The remainder is 68 after subtracting 712 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final outcome is 3937.08988, with a leftover of 6.8e-05.
