We look at the division of 45917393 by 870 
We're looking to find how many times 870 goes into 45917393.

On to step 1:
When dividing 4 by 870, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 870

Let's proceed to step 2:
The number 870 fits into 45 0 times, leaving a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Bring next digit (9) of the dividend behind the 45 and repeat the process: 459 / 870

Moving on to step 3:
If we divide 459 by 870, we get 0 and a remainder of 459.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 459 and we're left with 459.
Fetch the next digit (1) from the dividend, attach it to 459 and continue: 4591 / 870

Step 4:
The number 870 fits into 4591 5 times, leaving a remainder of 241.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 4350 from 4591 to get 241.
Include the next digit (7) from the dividend after 241, then repeat: 2417 / 870

Step 5:
870 can be fit into 2417 2 times, resulting in a remainder of 677.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Deduct 1740 from 2417 and we're left with 677.
Fetch the next digit (3) from the dividend, attach it to 677 and continue: 6773 / 870

Let's proceed to step 6:
When dividing 6773 by 870, we get 7 with a remainder of 683.
Write down 7 as next digit of the result. 
Result so far: 527.0
The remainder is 683 after subtracting 6090 from 6773.
Include the next digit (9) from the dividend after 683, then repeat: 6839 / 870

Let's proceed to step 7:
When dividing 6839 by 870, we get 7 with a remainder of 749.
The next digit of our result is 7. 
Result so far: 5277.0
Subtract 6090 from 6839 to get 749.
Include the next digit (3) from the dividend after 749, then repeat: 7493 / 870

Let's proceed to step 8:
870 can be fit into 7493 8 times, resulting in a remainder of 533.
Put 8 as the next digit of the answer. 
Result so far: 52778.0
If we subtract 6960 from 7493, we get 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Going ahead to step 9:
If we divide 5330 by 870, we get 6 and a remainder of 110.
Write down 6 as next digit of the result. 
Result so far: 52778.6
The remainder is 110 after subtracting 5220 from 5330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 10:
The number 870 fits into 1100 1 times, leaving a remainder of 230.
Write down 1 as next digit of the result. 
Result so far: 52778.61
The remainder is 230 after subtracting 870 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 11:
870 goes into 2300 2 times with a remainder of 560.
Put 2 as the next digit of the answer. 
Result so far: 52778.612
If we take 1740 away from 2300, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 12:
When dividing 5600 by 870, we get 6 with a remainder of 380.
The number 6 becomes the next digit in our result. 
Result so far: 52778.6126
If we subtract 5220 from 5600, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 13:
870 goes into 3800 4 times with a remainder of 320.
Put 4 as the next digit of the answer. 
Result so far: 52778.61264
Deduct 3480 from 3800 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 14:
The number 870 fits into 3200 3 times, leaving a remainder of 590.
Write down 3 as next digit of the result. 
Result so far: 52778.612643
Subtracting 2610 from 3200 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Advancing to step 15:
The number 870 fits into 5900 6 times, leaving a remainder of 680.
Use 6 as the next digit of our solution. 
Result so far: 52778.6126436
Subtracting 5220 from 5900 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 16:
870 goes into 6800 7 times with a remainder of 710.
Put 7 as the next digit of the answer. 
Result so far: 52778.61264367
Subtracting 6090 from 6800 leaves us with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

In conclusion, the division gives 52778.61264367 with a balance of 7.1e-07.
