Let's divide 61291034 by 357
The aim is to understand the frequency of 357 in 61291034.

Advancing to step 1:
When dividing 6 by 357, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 357

Going ahead to step 2:
If we divide 61 by 357, we get 0 and a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Fetch the next digit (2) from the dividend, attach it to 61 and continue: 612 / 357

On to step 3:
357 can be fit into 612 1 times, resulting in a remainder of 255.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 357 from 612 and we're left with 255.
Take the next digit (9) from the dividend and append it to 255, then repeat: 2559 / 357

Step 4:
357 can be fit into 2559 7 times, resulting in a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 2499 from 2559 to get 60.
Append the next digit (1) from the dividend to 60 and continue with: 601 / 357

Going ahead to step 5:
357 goes into 601 1 times with a remainder of 244.
Write down 1 as next digit of the result. 
Result so far: 171.0
Subtract 357 from 601 to get 244.
Take the next digit (0) from the dividend and append it to 244, then repeat: 2440 / 357

On to step 6:
357 can be fit into 2440 6 times, resulting in a remainder of 298.
Write down 6 as next digit of the result. 
Result so far: 1716.0
Subtract 2142 from 2440 to get 298.
Take the next digit (3) from the dividend and append it to 298, then repeat: 2983 / 357

On to step 7:
If we divide 2983 by 357, we get 8 and a remainder of 127.
The number 8 becomes the next digit in our result. 
Result so far: 17168.0
If we take 2856 away from 2983, we end up with 127.
Fetch the next digit (4) from the dividend, attach it to 127 and continue: 1274 / 357

Moving on to step 8:
The number 357 fits into 1274 3 times, leaving a remainder of 203.
Record the quotient 3 as the next digit in the result. 
Result so far: 171683.0
Subtracting 1071 from 1274 leaves us with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

On to step 9:
When dividing 2030 by 357, we get 5 with a remainder of 245.
Record the quotient 5 as the next digit in the result. 
Result so far: 171683.5
Subtract 1785 from 2030 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 10:
357 can be fit into 2450 6 times, resulting in a remainder of 308.
Record the quotient 6 as the next digit in the result. 
Result so far: 171683.56
If we take 2142 away from 2450, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 11:
3080 divided by 357 is 8 with a remainder of 224.
The next digit of our result is 8. 
Result so far: 171683.568
If we subtract 2856 from 3080, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 12:
When dividing 2240 by 357, we get 6 with a remainder of 98.
Put 6 as the next digit of the answer. 
Result so far: 171683.5686
Subtract 2142 from 2240 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 13:
If we divide 980 by 357, we get 2 and a remainder of 266.
The number 2 becomes the next digit in our result. 
Result so far: 171683.56862
If we subtract 714 from 980, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Advancing to step 14:
2660 divided by 357 is 7 with a remainder of 161.
The next digit of our result is 7. 
Result so far: 171683.568627
Subtracting 2499 from 2660 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Advancing to step 15:
The number 357 fits into 1610 4 times, leaving a remainder of 182.
The number 4 becomes the next digit in our result. 
Result so far: 171683.5686274
Subtracting 1428 from 1610 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Advancing to step 16:
The number 357 fits into 1820 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 171683.56862745
Deduct 1785 from 1820 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 171683.56862745 with a remainder of 3.5e-08.
