643128 ÷ 58 
We want to divide 643128 by 58.

Going ahead to step 1:
58 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 58

Going ahead to step 2:
If we divide 64 by 58, we get 1 and a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 58 from 64 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 58

Let's proceed to step 3:
If we divide 63 by 58, we get 1 and a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 58 from 63 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 58

Going ahead to step 4:
58 can be fit into 51 0 times, resulting in a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 110.0
Subtracting 0 from 51 leaves us with 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 58

Advancing to step 5:
512 divided by 58 is 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 1108.0
If we take 464 away from 512, we end up with 48.
Append the next digit (8) from the dividend to 48 and continue with: 488 / 58

Moving on to step 6:
When dividing 488 by 58, we get 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 11088.0
Deduct 464 from 488 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
240 divided by 58 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 11088.4
The remainder is 8 after subtracting 232 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
The number 58 fits into 80 1 times, leaving a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 11088.41
If we subtract 58 from 80, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
58 can be fit into 220 3 times, resulting in a remainder of 46.
The next digit of our result is 3. 
Result so far: 11088.413
Subtracting 174 from 220 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 10:
When dividing 460 by 58, we get 7 with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 11088.4137
Subtract 406 from 460 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 11:
58 can be fit into 540 9 times, resulting in a remainder of 18.
The next digit of our result is 9. 
Result so far: 11088.41379
If we take 522 away from 540, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
58 goes into 180 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 11088.413793
If we take 174 away from 180, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
58 can be fit into 60 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 11088.4137931
If we take 58 away from 60, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
20 divided by 58 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 11088.4137931
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 11088.4137931, with a leftover of 2e-08.
