43671870 ÷ 289 
We want to figure out the number of times 43671870 can be divided by 289.

Advancing to step 1:
When dividing 4 by 289, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 289

Going ahead to step 2:
289 goes into 43 0 times with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 289

Moving on to step 3:
289 goes into 436 1 times with a remainder of 147.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 289 away from 436, we end up with 147.
Bring next digit (7) of the dividend behind the 147 and repeat the process: 1477 / 289

Step 4:
If we divide 1477 by 289, we get 5 and a remainder of 32.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 1445 away from 1477, we end up with 32.
Append the next digit (1) from the dividend to 32 and continue with: 321 / 289

Let's proceed to step 5:
289 goes into 321 1 times with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 151.0
If we subtract 289 from 321, we get 32.
Fetch the next digit (8) from the dividend, attach it to 32 and continue: 328 / 289

Advancing to step 6:
289 can be fit into 328 1 times, resulting in a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1511.0
Deduct 289 from 328 and we're left with 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 289

Going ahead to step 7:
397 divided by 289 is 1 with a remainder of 108.
Write down 1 as next digit of the result. 
Result so far: 15111.0
Subtract 289 from 397 to get 108.
Fetch the next digit (0) from the dividend, attach it to 108 and continue: 1080 / 289

Moving on to step 8:
1080 divided by 289 is 3 with a remainder of 213.
The next digit of our result is 3. 
Result so far: 151113.0
Subtract 867 from 1080 to get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Advancing to step 9:
If we divide 2130 by 289, we get 7 and a remainder of 107.
Write down 7 as next digit of the result. 
Result so far: 151113.7
The remainder is 107 after subtracting 2023 from 2130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Moving on to step 10:
If we divide 1070 by 289, we get 3 and a remainder of 203.
Write down 3 as next digit of the result. 
Result so far: 151113.73
If we take 867 away from 1070, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Let's proceed to step 11:
When dividing 2030 by 289, we get 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 151113.737
If we subtract 2023 from 2030, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
If we divide 70 by 289, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 151113.737
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 13:
289 can be fit into 700 2 times, resulting in a remainder of 122.
The number 2 becomes the next digit in our result. 
Result so far: 151113.73702
Subtracting 578 from 700 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 14:
1220 divided by 289 is 4 with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 151113.737024
Subtracting 1156 from 1220 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 15:
When dividing 640 by 289, we get 2 with a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 151113.7370242
If we subtract 578 from 640, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 16:
The number 289 fits into 620 2 times, leaving a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 151113.73702422
Deduct 578 from 620 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 151113.73702422 with a balance of 4.2e-08.
