55953670 divided by 421 
Let's see how many times 421 fits into 55953670.

Moving on to step 1:
The number 421 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 421

Moving on to step 2:
421 goes into 55 0 times with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Append the next digit (9) from the dividend to 55 and continue with: 559 / 421

Let's proceed to step 3:
421 goes into 559 1 times with a remainder of 138.
The next digit of our result is 1. 
Result so far: 1.0
If we take 421 away from 559, we end up with 138.
Include the next digit (5) from the dividend after 138, then repeat: 1385 / 421

Step 4:
The number 421 fits into 1385 3 times, leaving a remainder of 122.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 1263 from 1385, we get 122.
Grab the next digit (3) from the dividend, add it to 122, then carry on: 1223 / 421

Going ahead to step 5:
421 can be fit into 1223 2 times, resulting in a remainder of 381.
Put 2 as the next digit of the answer. 
Result so far: 132.0
Deduct 842 from 1223 and we're left with 381.
Include the next digit (6) from the dividend after 381, then repeat: 3816 / 421

On to step 6:
3816 divided by 421 is 9 with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 1329.0
If we subtract 3789 from 3816, we get 27.
Fetch the next digit (7) from the dividend, attach it to 27 and continue: 277 / 421

Going ahead to step 7:
The number 421 fits into 277 0 times, leaving a remainder of 277.
Write down 0 as next digit of the result. 
Result so far: 13290.0
Deduct 0 from 277 and we're left with 277.
Grab the next digit (0) from the dividend, add it to 277, then carry on: 2770 / 421

Moving on to step 8:
The number 421 fits into 2770 6 times, leaving a remainder of 244.
Write down 6 as next digit of the result. 
Result so far: 132906.0
If we take 2526 away from 2770, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 9:
2440 divided by 421 is 5 with a remainder of 335.
The next digit of our result is 5. 
Result so far: 132906.5
If we take 2105 away from 2440, we end up with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 10:
When dividing 3350 by 421, we get 7 with a remainder of 403.
Record the quotient 7 as the next digit in the result. 
Result so far: 132906.57
The remainder is 403 after subtracting 2947 from 3350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Step 11:
4030 divided by 421 is 9 with a remainder of 241.
Use 9 as the next digit of our solution. 
Result so far: 132906.579
Subtracting 3789 from 4030 leaves us with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Going ahead to step 12:
When dividing 2410 by 421, we get 5 with a remainder of 305.
The next digit of our result is 5. 
Result so far: 132906.5795
If we take 2105 away from 2410, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Step 13:
421 can be fit into 3050 7 times, resulting in a remainder of 103.
Write down 7 as next digit of the result. 
Result so far: 132906.57957
If we take 2947 away from 3050, we end up with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Step 14:
421 can be fit into 1030 2 times, resulting in a remainder of 188.
The next digit of our result is 2. 
Result so far: 132906.579572
The remainder is 188 after subtracting 842 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 15:
421 can be fit into 1880 4 times, resulting in a remainder of 196.
The next digit of our result is 4. 
Result so far: 132906.5795724
If we take 1684 away from 1880, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 16:
421 can be fit into 1960 4 times, resulting in a remainder of 276.
Put 4 as the next digit of the answer. 
Result so far: 132906.57957244
Subtract 1684 from 1960 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

The final result is 132906.57957244 with a remainder of 2.76e-07.
