59181830 ÷ 421 
We want to figure out the number of times 59181830 can be divided by 421.

Advancing to step 1:
421 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 421

Moving on to step 2:
When dividing 59 by 421, we get 0 with a remainder of 59.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 59 leaves us with 59.
Include the next digit (1) from the dividend after 59, then repeat: 591 / 421

On to step 3:
When dividing 591 by 421, we get 1 with a remainder of 170.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 170 after subtracting 421 from 591.
Take the next digit (8) from the dividend and append it to 170, then repeat: 1708 / 421

Let's proceed to step 4:
421 can be fit into 1708 4 times, resulting in a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 1684 from 1708 to get 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 421

Moving on to step 5:
421 can be fit into 241 0 times, resulting in a remainder of 241.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
The remainder is 241 after subtracting 0 from 241.
Append the next digit (8) from the dividend to 241 and continue with: 2418 / 421

Step 6:
If we divide 2418 by 421, we get 5 and a remainder of 313.
Record the quotient 5 as the next digit in the result. 
Result so far: 1405.0
Deduct 2105 from 2418 and we're left with 313.
Append the next digit (3) from the dividend to 313 and continue with: 3133 / 421

Step 7:
If we divide 3133 by 421, we get 7 and a remainder of 186.
Put 7 as the next digit of the answer. 
Result so far: 14057.0
The remainder is 186 after subtracting 2947 from 3133.
Append the next digit (0) from the dividend to 186 and continue with: 1860 / 421

Going ahead to step 8:
If we divide 1860 by 421, we get 4 and a remainder of 176.
The number 4 becomes the next digit in our result. 
Result so far: 140574.0
Subtract 1684 from 1860 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 9:
1760 divided by 421 is 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 140574.4
The remainder is 76 after subtracting 1684 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
760 divided by 421 is 1 with a remainder of 339.
Put 1 as the next digit of the answer. 
Result so far: 140574.41
The remainder is 339 after subtracting 421 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Going ahead to step 11:
421 can be fit into 3390 8 times, resulting in a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 140574.418
If we take 3368 away from 3390, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 12:
220 divided by 421 is 0 with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 140574.418
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 13:
The number 421 fits into 2200 5 times, leaving a remainder of 95.
Put 5 as the next digit of the answer. 
Result so far: 140574.41805
Subtracting 2105 from 2200 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 14:
421 goes into 950 2 times with a remainder of 108.
The number 2 becomes the next digit in our result. 
Result so far: 140574.418052
The remainder is 108 after subtracting 842 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 15:
The number 421 fits into 1080 2 times, leaving a remainder of 238.
The number 2 becomes the next digit in our result. 
Result so far: 140574.4180522
Subtract 842 from 1080 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

The quotient of the division is 140574.4180522, and the remainder is 2.38e-06.
