Let's divide 55375497 by 421
We want to figure out the number of times 55375497 can be divided by 421.

Going ahead to step 1:
When dividing 5 by 421, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 421

Advancing to step 2:
55 divided by 421 is 0 with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Bring next digit (3) of the dividend behind the 55 and repeat the process: 553 / 421

Moving on to step 3:
553 divided by 421 is 1 with a remainder of 132.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 421 from 553 leaves us with 132.
Include the next digit (7) from the dividend after 132, then repeat: 1327 / 421

Going ahead to step 4:
421 can be fit into 1327 3 times, resulting in a remainder of 64.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 64 after subtracting 1263 from 1327.
Bring next digit (5) of the dividend behind the 64 and repeat the process: 645 / 421

On to step 5:
645 divided by 421 is 1 with a remainder of 224.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
Subtracting 421 from 645 leaves us with 224.
Append the next digit (4) from the dividend to 224 and continue with: 2244 / 421

Step 6:
2244 divided by 421 is 5 with a remainder of 139.
Write down 5 as next digit of the result. 
Result so far: 1315.0
If we take 2105 away from 2244, we end up with 139.
Bring next digit (9) of the dividend behind the 139 and repeat the process: 1399 / 421

Going ahead to step 7:
If we divide 1399 by 421, we get 3 and a remainder of 136.
Write down 3 as next digit of the result. 
Result so far: 13153.0
If we subtract 1263 from 1399, we get 136.
Grab the next digit (7) from the dividend, add it to 136, then carry on: 1367 / 421

Moving on to step 8:
If we divide 1367 by 421, we get 3 and a remainder of 104.
The number 3 becomes the next digit in our result. 
Result so far: 131533.0
If we take 1263 away from 1367, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 9:
The number 421 fits into 1040 2 times, leaving a remainder of 198.
Put 2 as the next digit of the answer. 
Result so far: 131533.2
Subtract 842 from 1040 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 10:
The number 421 fits into 1980 4 times, leaving a remainder of 296.
The next digit of our result is 4. 
Result so far: 131533.24
Deduct 1684 from 1980 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 11:
421 goes into 2960 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 131533.247
Deduct 2947 from 2960 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 12:
421 goes into 130 0 times with a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 131533.247
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 13:
421 goes into 1300 3 times with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 131533.24703
If we subtract 1263 from 1300, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 14:
If we divide 370 by 421, we get 0 and a remainder of 370.
Use 0 as the next digit of our solution. 
Result so far: 131533.24703
Subtract 0 from 370 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 15:
When dividing 3700 by 421, we get 8 with a remainder of 332.
Write down 8 as next digit of the result. 
Result so far: 131533.2470308
If we subtract 3368 from 3700, 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.

Let's proceed to step 16:
3320 divided by 421 is 7 with a remainder of 373.
The number 7 becomes the next digit in our result. 
Result so far: 131533.24703087
Subtracting 2947 from 3320 leaves us with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

After the division, we end up with 131533.24703087 and a remainder of 3.73e-07.
