45512157 ÷ 916 
Let's see how many times 916 fits into 45512157.

On to step 1:
916 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 916

Let's proceed to step 2:
916 goes into 45 0 times with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Fetch the next digit (5) from the dividend, attach it to 45 and continue: 455 / 916

Advancing to step 3:
916 can be fit into 455 0 times, resulting in a remainder of 455.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 455, we get 455.
Grab the next digit (1) from the dividend, add it to 455, then carry on: 4551 / 916

Step 4:
If we divide 4551 by 916, we get 4 and a remainder of 887.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 3664 away from 4551, we end up with 887.
Fetch the next digit (2) from the dividend, attach it to 887 and continue: 8872 / 916

Advancing to step 5:
916 goes into 8872 9 times with a remainder of 628.
The next digit of our result is 9. 
Result so far: 49.0
Deduct 8244 from 8872 and we're left with 628.
Append the next digit (1) from the dividend to 628 and continue with: 6281 / 916

On to step 6:
916 goes into 6281 6 times with a remainder of 785.
Put 6 as the next digit of the answer. 
Result so far: 496.0
Subtract 5496 from 6281 to get 785.
Append the next digit (5) from the dividend to 785 and continue with: 7855 / 916

Let's proceed to step 7:
The number 916 fits into 7855 8 times, leaving a remainder of 527.
Put 8 as the next digit of the answer. 
Result so far: 4968.0
Subtracting 7328 from 7855 leaves us with 527.
Take the next digit (7) from the dividend and append it to 527, then repeat: 5277 / 916

On to step 8:
916 can be fit into 5277 5 times, resulting in a remainder of 697.
The number 5 becomes the next digit in our result. 
Result so far: 49685.0
If we take 4580 away from 5277, we end up with 697.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6970, and continue the process.

Step 9:
6970 divided by 916 is 7 with a remainder of 558.
Use 7 as the next digit of our solution. 
Result so far: 49685.7
Deduct 6412 from 6970 and we're left with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Advancing to step 10:
5580 divided by 916 is 6 with a remainder of 84.
The next digit of our result is 6. 
Result so far: 49685.76
If we take 5496 away from 5580, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 11:
916 can be fit into 840 0 times, resulting in a remainder of 840.
Put 0 as the next digit of the answer. 
Result so far: 49685.76
Deduct 0 from 840 and we're left with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Let's proceed to step 12:
916 can be fit into 8400 9 times, resulting in a remainder of 156.
Use 9 as the next digit of our solution. 
Result so far: 49685.7609
If we take 8244 away from 8400, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 13:
When dividing 1560 by 916, we get 1 with a remainder of 644.
Write down 1 as next digit of the result. 
Result so far: 49685.76091
If we subtract 916 from 1560, we get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Let's proceed to step 14:
6440 divided by 916 is 7 with a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 49685.760917
If we subtract 6412 from 6440, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 15:
The number 916 fits into 280 0 times, leaving a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 49685.760917
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 16:
916 goes into 2800 3 times with a remainder of 52.
Record the quotient 3 as the next digit in the result. 
Result so far: 49685.76091703
If we subtract 2748 from 2800, we 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.

In conclusion, the division gives 49685.76091703 with a balance of 5.2e-08.
