60288989 ÷ 421 
Let's see how many times 421 fits into 60288989.

Step 1:
421 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 421

Let's proceed to step 2:
421 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Fetch the next digit (2) from the dividend, attach it to 60 and continue: 602 / 421

Advancing to step 3:
421 can be fit into 602 1 times, resulting in a remainder of 181.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 421 from 602 leaves us with 181.
Include the next digit (8) from the dividend after 181, then repeat: 1818 / 421

Going ahead to step 4:
421 can be fit into 1818 4 times, resulting in a remainder of 134.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 1684 from 1818, we get 134.
Fetch the next digit (8) from the dividend, attach it to 134 and continue: 1348 / 421

Going ahead to step 5:
The number 421 fits into 1348 3 times, leaving a remainder of 85.
Use 3 as the next digit of our solution. 
Result so far: 143.0
The remainder is 85 after subtracting 1263 from 1348.
Grab the next digit (9) from the dividend, add it to 85, then carry on: 859 / 421

Moving on to step 6:
421 goes into 859 2 times with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 1432.0
Subtract 842 from 859 to get 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 421

Moving on to step 7:
When dividing 178 by 421, we get 0 with a remainder of 178.
The next digit of our result is 0. 
Result so far: 14320.0
If we subtract 0 from 178, we get 178.
Append the next digit (9) from the dividend to 178 and continue with: 1789 / 421

On to step 8:
The number 421 fits into 1789 4 times, leaving a remainder of 105.
Record the quotient 4 as the next digit in the result. 
Result so far: 143204.0
If we subtract 1684 from 1789, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 9:
When dividing 1050 by 421, we get 2 with a remainder of 208.
Put 2 as the next digit of the answer. 
Result so far: 143204.2
Subtract 842 from 1050 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 10:
421 can be fit into 2080 4 times, resulting in a remainder of 396.
Record the quotient 4 as the next digit in the result. 
Result so far: 143204.24
The remainder is 396 after subtracting 1684 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 11:
3960 divided by 421 is 9 with a remainder of 171.
Put 9 as the next digit of the answer. 
Result so far: 143204.249
If we take 3789 away from 3960, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Going ahead to step 12:
421 can be fit into 1710 4 times, resulting in a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 143204.2494
The remainder is 26 after subtracting 1684 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 13:
421 can be fit into 260 0 times, resulting in a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 143204.2494
If we take 0 away from 260, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 14:
When dividing 2600 by 421, we get 6 with a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 143204.249406
Subtracting 2526 from 2600 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 15:
421 goes into 740 1 times with a remainder of 319.
The number 1 becomes the next digit in our result. 
Result so far: 143204.2494061
The remainder is 319 after subtracting 421 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

On to step 16:
The number 421 fits into 3190 7 times, leaving a remainder of 243.
The next digit of our result is 7. 
Result so far: 143204.24940617
Subtracting 2947 from 3190 leaves us with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

After the division, we end up with 143204.24940617 and a remainder of 2.43e-07.
