72458398 ÷ 34 
We're looking to find how many times 34 goes into 72458398.

Advancing to step 1:
34 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 34

Advancing to step 2:
72 divided by 34 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 68 from 72 and we're left with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 34

On to step 3:
34 goes into 44 1 times with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Deduct 34 from 44 and we're left with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 34

Step 4:
The number 34 fits into 105 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 213.0
The remainder is 3 after subtracting 102 from 105.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 34

Moving on to step 5:
38 divided by 34 is 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 2131.0
If we take 34 away from 38, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 34

Step 6:
If we divide 43 by 34, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 21311.0
Subtracting 34 from 43 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 34

On to step 7:
When dividing 99 by 34, we get 2 with a remainder of 31.
The number 2 becomes the next digit in our result. 
Result so far: 213112.0
If we subtract 68 from 99, we get 31.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 34

Advancing to step 8:
34 goes into 318 9 times with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 2131129.0
Subtract 306 from 318 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
The number 34 fits into 120 3 times, leaving a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 2131129.3
Subtracting 102 from 120 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
34 can be fit into 180 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 2131129.35
Deduct 170 from 180 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
The number 34 fits into 100 2 times, leaving a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 2131129.352
If we subtract 68 from 100, we 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.

Moving on to step 12:
When dividing 320 by 34, we get 9 with a remainder of 14.
The next digit of our result is 9. 
Result so far: 2131129.3529
If we take 306 away from 320, we end up 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.

Going ahead to step 13:
34 goes into 140 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 2131129.35294
Subtract 136 from 140 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
When dividing 40 by 34, we get 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 2131129.352941
Deduct 34 from 40 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 15:
60 divided by 34 is 1 with a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 2131129.3529411
If we subtract 34 from 60, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 2131129.3529411 with a remainder of 2.6e-07.
