42310589 divided by 397 
We're looking to find how many times 397 goes into 42310589.

On to step 1:
The number 397 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 397

Step 2:
397 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 397

Moving on to step 3:
397 goes into 423 1 times with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 397 away from 423, we end up with 26.
Append the next digit (1) from the dividend to 26 and continue with: 261 / 397

On to step 4:
397 can be fit into 261 0 times, resulting in a remainder of 261.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 261 and we're left with 261.
Grab the next digit (0) from the dividend, add it to 261, then carry on: 2610 / 397

Going ahead to step 5:
397 goes into 2610 6 times with a remainder of 228.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
If we take 2382 away from 2610, we end up with 228.
Include the next digit (5) from the dividend after 228, then repeat: 2285 / 397

Moving on to step 6:
397 goes into 2285 5 times with a remainder of 300.
Record the quotient 5 as the next digit in the result. 
Result so far: 1065.0
If we subtract 1985 from 2285, we get 300.
Fetch the next digit (8) from the dividend, attach it to 300 and continue: 3008 / 397

Step 7:
When dividing 3008 by 397, we get 7 with a remainder of 229.
Record the quotient 7 as the next digit in the result. 
Result so far: 10657.0
Subtract 2779 from 3008 to get 229.
Take the next digit (9) from the dividend and append it to 229, then repeat: 2299 / 397

On to step 8:
The number 397 fits into 2299 5 times, leaving a remainder of 314.
The number 5 becomes the next digit in our result. 
Result so far: 106575.0
If we take 1985 away from 2299, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

On to step 9:
397 goes into 3140 7 times with a remainder of 361.
Use 7 as the next digit of our solution. 
Result so far: 106575.7
Deduct 2779 from 3140 and we're left with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Let's proceed to step 10:
3610 divided by 397 is 9 with a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 106575.79
Deduct 3573 from 3610 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 11:
The number 397 fits into 370 0 times, leaving a remainder of 370.
The next digit of our result is 0. 
Result so far: 106575.79
Subtracting 0 from 370 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 12:
397 can be fit into 3700 9 times, resulting in a remainder of 127.
Put 9 as the next digit of the answer. 
Result so far: 106575.7909
Subtract 3573 from 3700 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Advancing to step 13:
1270 divided by 397 is 3 with a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 106575.79093
If we take 1191 away from 1270, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 14:
The number 397 fits into 790 1 times, leaving a remainder of 393.
Use 1 as the next digit of our solution. 
Result so far: 106575.790931
Subtract 397 from 790 to get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

On to step 15:
397 goes into 3930 9 times with a remainder of 357.
Use 9 as the next digit of our solution. 
Result so far: 106575.7909319
Deduct 3573 from 3930 and we're left with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Moving on to step 16:
397 goes into 3570 8 times with a remainder of 394.
Put 8 as the next digit of the answer. 
Result so far: 106575.79093198
Subtract 3176 from 3570 to get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

In conclusion, the division gives 106575.79093198 with a balance of 3.94e-07.
