58 can be fit into 83 1 times, resulting in a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 58 from 83, we get 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 58

Moving on to step 4:
58 can be fit into 257 4 times, resulting in a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 114.0
If we take 232 away from 257, we end up with 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 58

Going ahead to step 5:
When dividing 253 by 58, we get 4 with a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 1144.0
Deduct 232 from 253 and we're left with 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 58

Let's proceed to step 6:
210 divided by 58 is 3 with a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 11443.0
If we subtract 174 from 210, we get 36.
Bring next digit (9) of the dividend behind the 36 and repeat the process: 369 / 58

Moving on to step 7:
369 divided by 58 is 6 with a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 114436.0
Subtracting 348 from 369 leaves us with 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 58

Advancing to step 8:
58 goes into 210 3 times with a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 1144363.0
The remainder is 36 after subtracting 174 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
The number 58 fits into 360 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 1144363.6
Deduct 348 from 360 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
58 goes into 120 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 1144363.62
Deduct 116 from 120 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 11:
If we divide 40 by 58, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 1144363.62
Subtract 0 from 40 to 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.

Moving on to step 12:
The number 58 fits into 400 6 times, leaving a remainder of 52.
The next digit of our result is 6. 
Result so far: 1144363.6206
Subtract 348 from 400 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 13:
58 can be fit into 520 8 times, resulting in a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 1144363.62068
Subtract 464 from 520 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 14:
58 can be fit into 560 9 times, resulting in a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 1144363.620689
Subtracting 522 from 560 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 15:
58 can be fit into 380 6 times, resulting in a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 1144363.6206896
Subtracting 348 from 380 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 16:
If we divide 320 by 58, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 1144363.62068965
Subtract 290 from 320 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 1144363.62068965 with a balance of 3e-08.
