37859143 ÷ 971 
The aim is to understand the frequency of 971 in 37859143.

On to step 1:
If we divide 3 by 971, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 971

Step 2:
971 can be fit into 37 0 times, resulting in a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 971

Step 3:
971 goes into 378 0 times with a remainder of 378.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 378, we end up with 378.
Bring next digit (5) of the dividend behind the 378 and repeat the process: 3785 / 971

Moving on to step 4:
971 goes into 3785 3 times with a remainder of 872.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 2913 from 3785, we get 872.
Fetch the next digit (9) from the dividend, attach it to 872 and continue: 8729 / 971

Advancing to step 5:
8729 divided by 971 is 8 with a remainder of 961.
Put 8 as the next digit of the answer. 
Result so far: 38.0
Deduct 7768 from 8729 and we're left with 961.
Include the next digit (1) from the dividend after 961, then repeat: 9611 / 971

Let's proceed to step 6:
971 goes into 9611 9 times with a remainder of 872.
The next digit of our result is 9. 
Result so far: 389.0
Subtracting 8739 from 9611 leaves us with 872.
Grab the next digit (4) from the dividend, add it to 872, then carry on: 8724 / 971

Going ahead to step 7:
971 goes into 8724 8 times with a remainder of 956.
Record the quotient 8 as the next digit in the result. 
Result so far: 3898.0
Subtract 7768 from 8724 to get 956.
Grab the next digit (3) from the dividend, add it to 956, then carry on: 9563 / 971

Advancing to step 8:
971 can be fit into 9563 9 times, resulting in a remainder of 824.
Put 9 as the next digit of the answer. 
Result so far: 38989.0
If we subtract 8739 from 9563, we get 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

Going ahead to step 9:
If we divide 8240 by 971, we get 8 and a remainder of 472.
Put 8 as the next digit of the answer. 
Result so far: 38989.8
The remainder is 472 after subtracting 7768 from 8240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 10:
If we divide 4720 by 971, we get 4 and a remainder of 836.
The number 4 becomes the next digit in our result. 
Result so far: 38989.84
Subtract 3884 from 4720 to get 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

Let's proceed to step 11:
If we divide 8360 by 971, we get 8 and a remainder of 592.
The next digit of our result is 8. 
Result so far: 38989.848
If we subtract 7768 from 8360, we get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Advancing to step 12:
5920 divided by 971 is 6 with a remainder of 94.
The next digit of our result is 6. 
Result so far: 38989.8486
The remainder is 94 after subtracting 5826 from 5920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 13:
When dividing 940 by 971, we get 0 with a remainder of 940.
The number 0 becomes the next digit in our result. 
Result so far: 38989.8486
Subtract 0 from 940 to get 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

Advancing to step 14:
971 can be fit into 9400 9 times, resulting in a remainder of 661.
Write down 9 as next digit of the result. 
Result so far: 38989.848609
If we subtract 8739 from 9400, we get 661.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6610, and continue the process.

Let's proceed to step 15:
971 goes into 6610 6 times with a remainder of 784.
The number 6 becomes the next digit in our result. 
Result so far: 38989.8486096
The remainder is 784 after subtracting 5826 from 6610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Step 16:
If we divide 7840 by 971, we get 8 and a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 38989.84860968
Subtract 7768 from 7840 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 38989.84860968, and the remainder is 7.2e-08.
