Let's divide 21940978 by 156
The aim is to understand the frequency of 156 in 21940978.

Advancing to step 1:
When dividing 2 by 156, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 156

On to step 2:
156 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 156

Advancing to step 3:
The number 156 fits into 219 1 times, leaving a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 156 from 219 and we're left with 63.
Bring next digit (4) of the dividend behind the 63 and repeat the process: 634 / 156

Step 4:
156 goes into 634 4 times with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 624 from 634 to get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 156

Advancing to step 5:
156 goes into 100 0 times with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 140.0
If we subtract 0 from 100, we get 100.
Grab the next digit (9) from the dividend, add it to 100, then carry on: 1009 / 156

Let's proceed to step 6:
If we divide 1009 by 156, we get 6 and a remainder of 73.
Use 6 as the next digit of our solution. 
Result so far: 1406.0
Subtracting 936 from 1009 leaves us with 73.
Include the next digit (7) from the dividend after 73, then repeat: 737 / 156

Let's proceed to step 7:
The number 156 fits into 737 4 times, leaving a remainder of 113.
The next digit of our result is 4. 
Result so far: 14064.0
If we subtract 624 from 737, we get 113.
Grab the next digit (8) from the dividend, add it to 113, then carry on: 1138 / 156

Going ahead to step 8:
When dividing 1138 by 156, we get 7 with a remainder of 46.
Write down 7 as next digit of the result. 
Result so far: 140647.0
Deduct 1092 from 1138 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 9:
If we divide 460 by 156, we get 2 and a remainder of 148.
The number 2 becomes the next digit in our result. 
Result so far: 140647.2
The remainder is 148 after subtracting 312 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 10:
1480 divided by 156 is 9 with a remainder of 76.
Put 9 as the next digit of the answer. 
Result so far: 140647.29
Subtracting 1404 from 1480 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
156 can be fit into 760 4 times, resulting in a remainder of 136.
Record the quotient 4 as the next digit in the result. 
Result so far: 140647.294
Subtract 624 from 760 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 12:
156 can be fit into 1360 8 times, resulting in a remainder of 112.
Use 8 as the next digit of our solution. 
Result so far: 140647.2948
If we take 1248 away from 1360, we end up 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.

Going ahead to step 13:
1120 divided by 156 is 7 with a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 140647.29487
The remainder is 28 after subtracting 1092 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 14:
156 goes into 280 1 times with a remainder of 124.
Use 1 as the next digit of our solution. 
Result so far: 140647.294871
If we take 156 away from 280, we end up 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.

Advancing to step 15:
1240 divided by 156 is 7 with a remainder of 148.
Write down 7 as next digit of the result. 
Result so far: 140647.2948717
Deduct 1092 from 1240 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 16:
If we divide 1480 by 156, we get 9 and a remainder of 76.
The next digit of our result is 9. 
Result so far: 140647.29487179
If we subtract 1404 from 1480, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 140647.29487179, with a leftover of 7.6e-08.
