We're dividing 93439740 by 643 
Let's see how many times 643 fits into 93439740.

Moving on to step 1:
9 divided by 643 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 643

Advancing to step 2:
643 can be fit into 93 0 times, resulting in a remainder of 93.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 93 to get 93.
Include the next digit (4) from the dividend after 93, then repeat: 934 / 643

Advancing to step 3:
When dividing 934 by 643, we get 1 with a remainder of 291.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 643 from 934 leaves us with 291.
Grab the next digit (3) from the dividend, add it to 291, then carry on: 2913 / 643

On to step 4:
2913 divided by 643 is 4 with a remainder of 341.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 2572 from 2913 leaves us with 341.
Bring next digit (9) of the dividend behind the 341 and repeat the process: 3419 / 643

Let's proceed to step 5:
If we divide 3419 by 643, we get 5 and a remainder of 204.
Write down 5 as next digit of the result. 
Result so far: 145.0
Subtracting 3215 from 3419 leaves us with 204.
Grab the next digit (7) from the dividend, add it to 204, then carry on: 2047 / 643

Going ahead to step 6:
2047 divided by 643 is 3 with a remainder of 118.
Put 3 as the next digit of the answer. 
Result so far: 1453.0
The remainder is 118 after subtracting 1929 from 2047.
Bring next digit (4) of the dividend behind the 118 and repeat the process: 1184 / 643

Let's proceed to step 7:
643 goes into 1184 1 times with a remainder of 541.
The number 1 becomes the next digit in our result. 
Result so far: 14531.0
Subtracting 643 from 1184 leaves us with 541.
Grab the next digit (0) from the dividend, add it to 541, then carry on: 5410 / 643

On to step 8:
643 goes into 5410 8 times with a remainder of 266.
The number 8 becomes the next digit in our result. 
Result so far: 145318.0
If we take 5144 away from 5410, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Advancing to step 9:
643 can be fit into 2660 4 times, resulting in a remainder of 88.
Record the quotient 4 as the next digit in the result. 
Result so far: 145318.4
Deduct 2572 from 2660 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 10:
When dividing 880 by 643, we get 1 with a remainder of 237.
Write down 1 as next digit of the result. 
Result so far: 145318.41
If we take 643 away from 880, we end up with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Let's proceed to step 11:
The number 643 fits into 2370 3 times, leaving a remainder of 441.
The number 3 becomes the next digit in our result. 
Result so far: 145318.413
Subtracting 1929 from 2370 leaves us with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Going ahead to step 12:
643 can be fit into 4410 6 times, resulting in a remainder of 552.
The next digit of our result is 6. 
Result so far: 145318.4136
The remainder is 552 after subtracting 3858 from 4410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Let's proceed to step 13:
The number 643 fits into 5520 8 times, leaving a remainder of 376.
The next digit of our result is 8. 
Result so far: 145318.41368
Subtracting 5144 from 5520 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 14:
If we divide 3760 by 643, we get 5 and a remainder of 545.
Write down 5 as next digit of the result. 
Result so far: 145318.413685
Subtracting 3215 from 3760 leaves us with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Let's proceed to step 15:
If we divide 5450 by 643, we get 8 and a remainder of 306.
The number 8 becomes the next digit in our result. 
Result so far: 145318.4136858
The remainder is 306 after subtracting 5144 from 5450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 16:
If we divide 3060 by 643, we get 4 and a remainder of 488.
The next digit of our result is 4. 
Result so far: 145318.41368584
Subtract 2572 from 3060 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

The final result is 145318.41368584 with a remainder of 4.88e-07.
