We divide 57515534 by 421
The aim is to understand the frequency of 421 in 57515534.

Let's proceed to step 1:
421 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 421

Let's proceed to step 2:
421 can be fit into 57 0 times, resulting in a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Bring next digit (5) of the dividend behind the 57 and repeat the process: 575 / 421

Advancing to step 3:
421 goes into 575 1 times with a remainder of 154.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 421 away from 575, we end up with 154.
Fetch the next digit (1) from the dividend, attach it to 154 and continue: 1541 / 421

Going ahead to step 4:
The number 421 fits into 1541 3 times, leaving a remainder of 278.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 1263 from 1541 to get 278.
Grab the next digit (5) from the dividend, add it to 278, then carry on: 2785 / 421

Let's proceed to step 5:
2785 divided by 421 is 6 with a remainder of 259.
Put 6 as the next digit of the answer. 
Result so far: 136.0
Subtract 2526 from 2785 to get 259.
Append the next digit (5) from the dividend to 259 and continue with: 2595 / 421

Moving on to step 6:
When dividing 2595 by 421, we get 6 with a remainder of 69.
Record the quotient 6 as the next digit in the result. 
Result so far: 1366.0
Deduct 2526 from 2595 and we're left with 69.
Include the next digit (3) from the dividend after 69, then repeat: 693 / 421

Moving on to step 7:
421 goes into 693 1 times with a remainder of 272.
Record the quotient 1 as the next digit in the result. 
Result so far: 13661.0
If we subtract 421 from 693, we get 272.
Grab the next digit (4) from the dividend, add it to 272, then carry on: 2724 / 421

Let's proceed to step 8:
The number 421 fits into 2724 6 times, leaving a remainder of 198.
The number 6 becomes the next digit in our result. 
Result so far: 136616.0
If we take 2526 away from 2724, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 9:
When dividing 1980 by 421, we get 4 with a remainder of 296.
The number 4 becomes the next digit in our result. 
Result so far: 136616.4
Subtracting 1684 from 1980 leaves us 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.

Let's proceed to step 10:
421 goes into 2960 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 136616.47
Subtract 2947 from 2960 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 11:
If we divide 130 by 421, we get 0 and a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 136616.47
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 12:
The number 421 fits into 1300 3 times, leaving a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 136616.4703
Subtracting 1263 from 1300 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 13:
The number 421 fits into 370 0 times, leaving a remainder of 370.
The next digit of our result is 0. 
Result so far: 136616.4703
Subtracting 0 from 370 leaves us with 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 14:
The number 421 fits into 3700 8 times, leaving a remainder of 332.
Put 8 as the next digit of the answer. 
Result so far: 136616.470308
The remainder is 332 after subtracting 3368 from 3700.
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 15:
3320 divided by 421 is 7 with a remainder of 373.
The number 7 becomes the next digit in our result. 
Result so far: 136616.4703087
The remainder is 373 after subtracting 2947 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

On to step 16:
421 goes into 3730 8 times with a remainder of 362.
Write down 8 as next digit of the result. 
Result so far: 136616.47030878
If we take 3368 away from 3730, we end up with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Our division results in 136616.47030878 with a remaining 3.62e-07.
