66156395 ÷ 943 
The aim is to understand the frequency of 943 in 66156395.

Advancing to step 1:
When dividing 6 by 943, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 943

Step 2:
943 goes into 66 0 times with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 943

Let's proceed to step 3:
943 can be fit into 661 0 times, resulting in a remainder of 661.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 661 leaves us with 661.
Append the next digit (5) from the dividend to 661 and continue with: 6615 / 943

Let's proceed to step 4:
943 can be fit into 6615 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 6601 away from 6615, we end up with 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 943

Moving on to step 5:
943 goes into 146 0 times with a remainder of 146.
The next digit of our result is 0. 
Result so far: 70.0
Deduct 0 from 146 and we're left with 146.
Take the next digit (3) from the dividend and append it to 146, then repeat: 1463 / 943

Let's proceed to step 6:
The number 943 fits into 1463 1 times, leaving a remainder of 520.
Record the quotient 1 as the next digit in the result. 
Result so far: 701.0
If we subtract 943 from 1463, we get 520.
Fetch the next digit (9) from the dividend, attach it to 520 and continue: 5209 / 943

On to step 7:
If we divide 5209 by 943, we get 5 and a remainder of 494.
Write down 5 as next digit of the result. 
Result so far: 7015.0
If we subtract 4715 from 5209, we get 494.
Append the next digit (5) from the dividend to 494 and continue with: 4945 / 943

Let's proceed to step 8:
When dividing 4945 by 943, we get 5 with a remainder of 230.
The number 5 becomes the next digit in our result. 
Result so far: 70155.0
If we subtract 4715 from 4945, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 9:
943 goes into 2300 2 times with a remainder of 414.
Put 2 as the next digit of the answer. 
Result so far: 70155.2
Deduct 1886 from 2300 and we're left with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Advancing to step 10:
943 can be fit into 4140 4 times, resulting in a remainder of 368.
Write down 4 as next digit of the result. 
Result so far: 70155.24
If we subtract 3772 from 4140, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 11:
The number 943 fits into 3680 3 times, leaving a remainder of 851.
Use 3 as the next digit of our solution. 
Result so far: 70155.243
Subtract 2829 from 3680 to get 851.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8510, and continue the process.

Moving on to step 12:
943 goes into 8510 9 times with a remainder of 23.
The next digit of our result is 9. 
Result so far: 70155.2439
If we subtract 8487 from 8510, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 13:
If we divide 230 by 943, we get 0 and a remainder of 230.
Record the quotient 0 as the next digit in the result. 
Result so far: 70155.2439
Deduct 0 from 230 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 14:
The number 943 fits into 2300 2 times, leaving a remainder of 414.
Record the quotient 2 as the next digit in the result. 
Result so far: 70155.243902
Subtracting 1886 from 2300 leaves us with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 15:
When dividing 4140 by 943, we get 4 with a remainder of 368.
Record the quotient 4 as the next digit in the result. 
Result so far: 70155.2439024
Subtract 3772 from 4140 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 16:
When dividing 3680 by 943, we get 3 with a remainder of 851.
Record the quotient 3 as the next digit in the result. 
Result so far: 70155.24390243
Deduct 2829 from 3680 and we're left with 851.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8510, and continue the process.

The final outcome is 70155.24390243, with a leftover of 8.51e-07.
