We look at the division of 59355319 by 421 
Our goal is to divide 59355319 by 421.

Going ahead 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
Deduct 0 from 5 and we're left with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 421

Going ahead to step 2:
421 goes into 59 0 times with a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 59 to get 59.
Take the next digit (3) from the dividend and append it to 59, then repeat: 593 / 421

Advancing to step 3:
421 goes into 593 1 times with a remainder of 172.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 421 from 593, we get 172.
Append the next digit (5) from the dividend to 172 and continue with: 1725 / 421

Moving on to step 4:
If we divide 1725 by 421, we get 4 and a remainder of 41.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 41 after subtracting 1684 from 1725.
Take the next digit (5) from the dividend and append it to 41, then repeat: 415 / 421

Going ahead to step 5:
If we divide 415 by 421, we get 0 and a remainder of 415.
Put 0 as the next digit of the answer. 
Result so far: 140.0
Subtracting 0 from 415 leaves us with 415.
Append the next digit (3) from the dividend to 415 and continue with: 4153 / 421

Step 6:
When dividing 4153 by 421, we get 9 with a remainder of 364.
The number 9 becomes the next digit in our result. 
Result so far: 1409.0
If we take 3789 away from 4153, we end up with 364.
Grab the next digit (1) from the dividend, add it to 364, then carry on: 3641 / 421

Advancing to step 7:
3641 divided by 421 is 8 with a remainder of 273.
Record the quotient 8 as the next digit in the result. 
Result so far: 14098.0
Subtract 3368 from 3641 to get 273.
Bring next digit (9) of the dividend behind the 273 and repeat the process: 2739 / 421

Step 8:
When dividing 2739 by 421, we get 6 with a remainder of 213.
The number 6 becomes the next digit in our result. 
Result so far: 140986.0
Subtract 2526 from 2739 to get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Advancing to step 9:
421 goes into 2130 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 140986.5
The remainder is 25 after subtracting 2105 from 2130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 10:
The number 421 fits into 250 0 times, leaving a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 140986.5
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 11:
If we divide 2500 by 421, we get 5 and a remainder of 395.
Write down 5 as next digit of the result. 
Result so far: 140986.505
The remainder is 395 after subtracting 2105 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Let's proceed to step 12:
When dividing 3950 by 421, we get 9 with a remainder of 161.
Write down 9 as next digit of the result. 
Result so far: 140986.5059
If we subtract 3789 from 3950, we get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Moving on to step 13:
1610 divided by 421 is 3 with a remainder of 347.
Put 3 as the next digit of the answer. 
Result so far: 140986.50593
If we take 1263 away from 1610, we end up with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Step 14:
The number 421 fits into 3470 8 times, leaving a remainder of 102.
Use 8 as the next digit of our solution. 
Result so far: 140986.505938
Subtract 3368 from 3470 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 15:
When dividing 1020 by 421, we get 2 with a remainder of 178.
Put 2 as the next digit of the answer. 
Result so far: 140986.5059382
Subtracting 842 from 1020 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 16:
If we divide 1780 by 421, we get 4 and a remainder of 96.
Put 4 as the next digit of the answer. 
Result so far: 140986.50593824
Subtract 1684 from 1780 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

After the division, we end up with 140986.50593824 and a remainder of 9.6e-08.
