We're dividing 70931738 by 146 
The aim is to understand the frequency of 146 in 70931738.

Advancing to step 1:
If we divide 7 by 146, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 146

On to step 2:
When dividing 70 by 146, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Bring next digit (9) of the dividend behind the 70 and repeat the process: 709 / 146

Going ahead to step 3:
146 goes into 709 4 times with a remainder of 125.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 584 from 709 and we're left with 125.
Fetch the next digit (3) from the dividend, attach it to 125 and continue: 1253 / 146

Going ahead to step 4:
When dividing 1253 by 146, we get 8 with a remainder of 85.
The next digit of our result is 8. 
Result so far: 48.0
Subtract 1168 from 1253 to get 85.
Take the next digit (1) from the dividend and append it to 85, then repeat: 851 / 146

Let's proceed to step 5:
When dividing 851 by 146, we get 5 with a remainder of 121.
Put 5 as the next digit of the answer. 
Result so far: 485.0
If we take 730 away from 851, we end up with 121.
Fetch the next digit (7) from the dividend, attach it to 121 and continue: 1217 / 146

Step 6:
146 goes into 1217 8 times with a remainder of 49.
Write down 8 as next digit of the result. 
Result so far: 4858.0
If we subtract 1168 from 1217, we get 49.
Bring next digit (3) of the dividend behind the 49 and repeat the process: 493 / 146

Advancing to step 7:
If we divide 493 by 146, we get 3 and a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 48583.0
If we take 438 away from 493, we end up with 55.
Append the next digit (8) from the dividend to 55 and continue with: 558 / 146

Moving on to step 8:
146 can be fit into 558 3 times, resulting in a remainder of 120.
Record the quotient 3 as the next digit in the result. 
Result so far: 485833.0
If we take 438 away from 558, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 9:
146 goes into 1200 8 times with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 485833.8
The remainder is 32 after subtracting 1168 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
When dividing 320 by 146, we get 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 485833.82
If we subtract 292 from 320, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
146 can be fit into 280 1 times, resulting in a remainder of 134.
Write down 1 as next digit of the result. 
Result so far: 485833.821
Subtract 146 from 280 to 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.

Advancing to step 12:
1340 divided by 146 is 9 with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 485833.8219
If we subtract 1314 from 1340, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
146 goes into 260 1 times with a remainder of 114.
Use 1 as the next digit of our solution. 
Result so far: 485833.82191
The remainder is 114 after subtracting 146 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 14:
When dividing 1140 by 146, we get 7 with a remainder of 118.
Put 7 as the next digit of the answer. 
Result so far: 485833.821917
The remainder is 118 after subtracting 1022 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 15:
The number 146 fits into 1180 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 485833.8219178
The remainder is 12 after subtracting 1168 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 16:
146 can be fit into 120 0 times, resulting in a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 485833.8219178
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

In conclusion, the division gives 485833.8219178 with a balance of 1.2e-07.
