68735858 ÷ 489 
We want to figure out the number of times 68735858 can be divided by 489.

On to step 1:
When dividing 6 by 489, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 489

Let's proceed to step 2:
If we divide 68 by 489, we get 0 and a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Append the next digit (7) from the dividend to 68 and continue with: 687 / 489

On to step 3:
687 divided by 489 is 1 with a remainder of 198.
The next digit of our result is 1. 
Result so far: 1.0
If we take 489 away from 687, we end up with 198.
Append the next digit (3) from the dividend to 198 and continue with: 1983 / 489

Going ahead to step 4:
489 can be fit into 1983 4 times, resulting in a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 1956 from 1983, we get 27.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 489

Advancing to step 5:
If we divide 275 by 489, we get 0 and a remainder of 275.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
If we subtract 0 from 275, we get 275.
Take the next digit (8) from the dividend and append it to 275, then repeat: 2758 / 489

Moving on to step 6:
If we divide 2758 by 489, we get 5 and a remainder of 313.
Write down 5 as next digit of the result. 
Result so far: 1405.0
Subtract 2445 from 2758 to get 313.
Grab the next digit (5) from the dividend, add it to 313, then carry on: 3135 / 489

Moving on to step 7:
489 goes into 3135 6 times with a remainder of 201.
The next digit of our result is 6. 
Result so far: 14056.0
Subtracting 2934 from 3135 leaves us with 201.
Fetch the next digit (8) from the dividend, attach it to 201 and continue: 2018 / 489

Advancing to step 8:
The number 489 fits into 2018 4 times, leaving a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 140564.0
Subtracting 1956 from 2018 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 9:
489 can be fit into 620 1 times, resulting in a remainder of 131.
Record the quotient 1 as the next digit in the result. 
Result so far: 140564.1
The remainder is 131 after subtracting 489 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 10:
The number 489 fits into 1310 2 times, leaving a remainder of 332.
Use 2 as the next digit of our solution. 
Result so far: 140564.12
If we subtract 978 from 1310, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 11:
When dividing 3320 by 489, we get 6 with a remainder of 386.
The number 6 becomes the next digit in our result. 
Result so far: 140564.126
The remainder is 386 after subtracting 2934 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

On to step 12:
If we divide 3860 by 489, we get 7 and a remainder of 437.
The number 7 becomes the next digit in our result. 
Result so far: 140564.1267
The remainder is 437 after subtracting 3423 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Advancing to step 13:
When dividing 4370 by 489, we get 8 with a remainder of 458.
The number 8 becomes the next digit in our result. 
Result so far: 140564.12678
The remainder is 458 after subtracting 3912 from 4370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

On to step 14:
4580 divided by 489 is 9 with a remainder of 179.
Write down 9 as next digit of the result. 
Result so far: 140564.126789
Subtract 4401 from 4580 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Advancing to step 15:
489 goes into 1790 3 times with a remainder of 323.
Write down 3 as next digit of the result. 
Result so far: 140564.1267893
Subtracting 1467 from 1790 leaves us with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Moving on to step 16:
When dividing 3230 by 489, we get 6 with a remainder of 296.
Put 6 as the next digit of the answer. 
Result so far: 140564.12678936
Subtract 2934 from 3230 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

After the division, we end up with 140564.12678936 and a remainder of 2.96e-07.
