Let's divide 343399 by 89
Let's see how many times 89 fits into 343399.

Moving on to step 1:
89 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 89

Advancing to step 2:
If we divide 34 by 89, we get 0 and a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Bring next digit (3) of the dividend behind the 34 and repeat the process: 343 / 89

Step 3:
89 goes into 343 3 times with a remainder of 76.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 267 from 343 and we're left with 76.
Append the next digit (3) from the dividend to 76 and continue with: 763 / 89

Advancing to step 4:
89 can be fit into 763 8 times, resulting in a remainder of 51.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Deduct 712 from 763 and we're left with 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 89

Moving on to step 5:
519 divided by 89 is 5 with a remainder of 74.
Record the quotient 5 as the next digit in the result. 
Result so far: 385.0
Subtract 445 from 519 to get 74.
Grab the next digit (9) from the dividend, add it to 74, then carry on: 749 / 89

Advancing to step 6:
89 can be fit into 749 8 times, resulting in a remainder of 37.
The number 8 becomes the next digit in our result. 
Result so far: 3858.0
If we take 712 away from 749, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 7:
When dividing 370 by 89, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 3858.4
Deduct 356 from 370 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
If we divide 140 by 89, we get 1 and a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 3858.41
If we take 89 away from 140, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 9:
The number 89 fits into 510 5 times, leaving a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 3858.415
Subtract 445 from 510 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 10:
89 can be fit into 650 7 times, resulting in a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 3858.4157
If we take 623 away from 650, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 11:
The number 89 fits into 270 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3858.41573
Subtract 267 from 270 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
89 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 3858.41573
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
The number 89 fits into 300 3 times, leaving a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 3858.4157303
Subtract 267 from 300 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 14:
The number 89 fits into 330 3 times, leaving a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 3858.41573033
The remainder is 63 after subtracting 267 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

After the division, we end up with 3858.41573033 and a remainder of 6.3e-08.
