43987342 divided by 629 
We want to figure out the number of times 43987342 can be divided by 629.

Going ahead to step 1:
When dividing 4 by 629, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 629

On to step 2:
If we divide 43 by 629, we get 0 and a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Fetch the next digit (9) from the dividend, attach it to 43 and continue: 439 / 629

Let's proceed to step 3:
629 can be fit into 439 0 times, resulting in a remainder of 439.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 439 and we're left with 439.
Include the next digit (8) from the dividend after 439, then repeat: 4398 / 629

Going ahead to step 4:
629 goes into 4398 6 times with a remainder of 624.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 3774 from 4398 and we're left with 624.
Append the next digit (7) from the dividend to 624 and continue with: 6247 / 629

On to step 5:
When dividing 6247 by 629, we get 9 with a remainder of 586.
Write down 9 as next digit of the result. 
Result so far: 69.0
Deduct 5661 from 6247 and we're left with 586.
Take the next digit (3) from the dividend and append it to 586, then repeat: 5863 / 629

Step 6:
When dividing 5863 by 629, we get 9 with a remainder of 202.
The next digit of our result is 9. 
Result so far: 699.0
If we subtract 5661 from 5863, we get 202.
Include the next digit (4) from the dividend after 202, then repeat: 2024 / 629

Going ahead to step 7:
629 goes into 2024 3 times with a remainder of 137.
Record the quotient 3 as the next digit in the result. 
Result so far: 6993.0
Subtract 1887 from 2024 to get 137.
Bring next digit (2) of the dividend behind the 137 and repeat the process: 1372 / 629

Going ahead to step 8:
If we divide 1372 by 629, we get 2 and a remainder of 114.
The next digit of our result is 2. 
Result so far: 69932.0
Subtract 1258 from 1372 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 9:
The number 629 fits into 1140 1 times, leaving a remainder of 511.
Write down 1 as next digit of the result. 
Result so far: 69932.1
If we take 629 away from 1140, we end up with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Let's proceed to step 10:
The number 629 fits into 5110 8 times, leaving a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 69932.18
If we subtract 5032 from 5110, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 11:
When dividing 780 by 629, we get 1 with a remainder of 151.
Use 1 as the next digit of our solution. 
Result so far: 69932.181
Deduct 629 from 780 and we're left with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Advancing to step 12:
If we divide 1510 by 629, we get 2 and a remainder of 252.
The next digit of our result is 2. 
Result so far: 69932.1812
If we take 1258 away from 1510, we end up 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.

Going ahead to step 13:
When dividing 2520 by 629, we get 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 69932.18124
Deduct 2516 from 2520 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.

Moving on to step 14:
The number 629 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 69932.18124
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 15:
If we divide 400 by 629, we get 0 and a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 69932.18124
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 69932.18124, with a leftover of 4e-06.
