We divide 91171531 by 141
The aim is to understand the frequency of 141 in 91171531.

On to step 1:
If we divide 9 by 141, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 141

On to step 2:
The number 141 fits into 91 0 times, leaving a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Append the next digit (1) from the dividend to 91 and continue with: 911 / 141

Going ahead to step 3:
141 can be fit into 911 6 times, resulting in a remainder of 65.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 846 from 911 and we're left with 65.
Fetch the next digit (7) from the dividend, attach it to 65 and continue: 657 / 141

Let's proceed to step 4:
If we divide 657 by 141, we get 4 and a remainder of 93.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
If we take 564 away from 657, we end up with 93.
Take the next digit (1) from the dividend and append it to 93, then repeat: 931 / 141

On to step 5:
141 goes into 931 6 times with a remainder of 85.
The number 6 becomes the next digit in our result. 
Result so far: 646.0
If we subtract 846 from 931, we get 85.
Fetch the next digit (5) from the dividend, attach it to 85 and continue: 855 / 141

Going ahead to step 6:
The number 141 fits into 855 6 times, leaving a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 6466.0
Subtracting 846 from 855 leaves us with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 141

Step 7:
If we divide 93 by 141, we get 0 and a remainder of 93.
The number 0 becomes the next digit in our result. 
Result so far: 64660.0
Subtract 0 from 93 to get 93.
Include the next digit (1) from the dividend after 93, then repeat: 931 / 141

Let's proceed to step 8:
141 can be fit into 931 6 times, resulting in a remainder of 85.
Record the quotient 6 as the next digit in the result. 
Result so far: 646606.0
The remainder is 85 after subtracting 846 from 931.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 9:
If we divide 850 by 141, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 646606.6
Deduct 846 from 850 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
141 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 646606.6
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
If we divide 400 by 141, we get 2 and a remainder of 118.
Use 2 as the next digit of our solution. 
Result so far: 646606.602
If we subtract 282 from 400, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 12:
141 goes into 1180 8 times with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 646606.6028
Deduct 1128 from 1180 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 13:
141 can be fit into 520 3 times, resulting in a remainder of 97.
Record the quotient 3 as the next digit in the result. 
Result so far: 646606.60283
The remainder is 97 after subtracting 423 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 14:
970 divided by 141 is 6 with a remainder of 124.
The next digit of our result is 6. 
Result so far: 646606.602836
Subtracting 846 from 970 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 15:
When dividing 1240 by 141, we get 8 with a remainder of 112.
The number 8 becomes the next digit in our result. 
Result so far: 646606.6028368
Deduct 1128 from 1240 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 16:
1120 divided by 141 is 7 with a remainder of 133.
Put 7 as the next digit of the answer. 
Result so far: 646606.60283687
Subtracting 987 from 1120 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

The quotient of the division is 646606.60283687, and the remainder is 1.33e-07.
