Let's divide 31691974 by 278
The aim is to understand the frequency of 278 in 31691974.

On to step 1:
278 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 278

On to step 2:
If we divide 31 by 278, we get 0 and a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Include the next digit (6) from the dividend after 31, then repeat: 316 / 278

Advancing to step 3:
278 goes into 316 1 times with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 278 away from 316, we end up with 38.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 278

Advancing to step 4:
278 goes into 389 1 times with a remainder of 111.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 111 after subtracting 278 from 389.
Bring next digit (1) of the dividend behind the 111 and repeat the process: 1111 / 278

Moving on to step 5:
278 can be fit into 1111 3 times, resulting in a remainder of 277.
Put 3 as the next digit of the answer. 
Result so far: 113.0
If we take 834 away from 1111, we end up with 277.
Bring next digit (9) of the dividend behind the 277 and repeat the process: 2779 / 278

Step 6:
2779 divided by 278 is 9 with a remainder of 277.
Use 9 as the next digit of our solution. 
Result so far: 1139.0
If we take 2502 away from 2779, we end up with 277.
Append the next digit (7) from the dividend to 277 and continue with: 2777 / 278

Going ahead to step 7:
278 can be fit into 2777 9 times, resulting in a remainder of 275.
Write down 9 as next digit of the result. 
Result so far: 11399.0
Subtracting 2502 from 2777 leaves us with 275.
Fetch the next digit (4) from the dividend, attach it to 275 and continue: 2754 / 278

Going ahead to step 8:
If we divide 2754 by 278, we get 9 and a remainder of 252.
Write down 9 as next digit of the result. 
Result so far: 113999.0
Subtracting 2502 from 2754 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 9:
If we divide 2520 by 278, we get 9 and a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 113999.9
Subtract 2502 from 2520 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
180 divided by 278 is 0 with a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 113999.9
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
If we divide 1800 by 278, we get 6 and a remainder of 132.
Put 6 as the next digit of the answer. 
Result so far: 113999.906
If we subtract 1668 from 1800, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 12:
When dividing 1320 by 278, we get 4 with a remainder of 208.
The number 4 becomes the next digit in our result. 
Result so far: 113999.9064
If we subtract 1112 from 1320, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 13:
When dividing 2080 by 278, we get 7 with a remainder of 134.
Write down 7 as next digit of the result. 
Result so far: 113999.90647
If we subtract 1946 from 2080, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 14:
When dividing 1340 by 278, we get 4 with a remainder of 228.
Write down 4 as next digit of the result. 
Result so far: 113999.906474
Subtract 1112 from 1340 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 15:
278 can be fit into 2280 8 times, resulting in a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 113999.9064748
Deduct 2224 from 2280 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 16:
If we divide 560 by 278, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 113999.90647482
Deduct 556 from 560 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.

The final outcome is 113999.90647482, with a leftover of 4e-09.
