We divide 17373579 by 141
The aim is to understand the frequency of 141 in 17373579.

Let's proceed to step 1:
141 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 141

On to step 2:
17 divided by 141 is 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 141

Step 3:
The number 141 fits into 173 1 times, leaving a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 141 from 173, we get 32.
Grab the next digit (7) from the dividend, add it to 32, then carry on: 327 / 141

Advancing to step 4:
327 divided by 141 is 2 with a remainder of 45.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 282 from 327 leaves us with 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 141

Going ahead to step 5:
The number 141 fits into 453 3 times, leaving a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 123.0
If we subtract 423 from 453, we get 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 141

On to step 6:
The number 141 fits into 305 2 times, leaving a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 1232.0
Subtract 282 from 305 to get 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 141

Advancing to step 7:
141 goes into 237 1 times with a remainder of 96.
The next digit of our result is 1. 
Result so far: 12321.0
The remainder is 96 after subtracting 141 from 237.
Fetch the next digit (9) from the dividend, attach it to 96 and continue: 969 / 141

On to step 8:
The number 141 fits into 969 6 times, leaving a remainder of 123.
The next digit of our result is 6. 
Result so far: 123216.0
If we take 846 away from 969, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 9:
141 goes into 1230 8 times with a remainder of 102.
The next digit of our result is 8. 
Result so far: 123216.8
Deduct 1128 from 1230 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 10:
The number 141 fits into 1020 7 times, leaving a remainder of 33.
The next digit of our result is 7. 
Result so far: 123216.87
If we subtract 987 from 1020, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 11:
If we divide 330 by 141, we get 2 and a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 123216.872
Subtract 282 from 330 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
The number 141 fits into 480 3 times, leaving a remainder of 57.
The next digit of our result is 3. 
Result so far: 123216.8723
Deduct 423 from 480 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 13:
141 can be fit into 570 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 123216.87234
Deduct 564 from 570 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
141 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 123216.87234
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 15:
When dividing 600 by 141, we get 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 123216.8723404
Subtract 564 from 600 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 16:
The number 141 fits into 360 2 times, leaving a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 123216.87234042
If we take 282 away from 360, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

After the division, we end up with 123216.87234042 and a remainder of 7.8e-08.
