We're dividing 61590159 by 816 
Our goal is to divide 61590159 by 816.

Let's proceed to step 1:
If we divide 6 by 816, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 816

Moving on to step 2:
816 goes into 61 0 times with a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Append the next digit (5) from the dividend to 61 and continue with: 615 / 816

Advancing to step 3:
The number 816 fits into 615 0 times, leaving a remainder of 615.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 615 to get 615.
Include the next digit (9) from the dividend after 615, then repeat: 6159 / 816

Advancing to step 4:
816 goes into 6159 7 times with a remainder of 447.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 5712 away from 6159, we end up with 447.
Include the next digit (0) from the dividend after 447, then repeat: 4470 / 816

On to step 5:
When dividing 4470 by 816, we get 5 with a remainder of 390.
Write down 5 as next digit of the result. 
Result so far: 75.0
The remainder is 390 after subtracting 4080 from 4470.
Bring next digit (1) of the dividend behind the 390 and repeat the process: 3901 / 816

Going ahead to step 6:
816 can be fit into 3901 4 times, resulting in a remainder of 637.
Write down 4 as next digit of the result. 
Result so far: 754.0
Deduct 3264 from 3901 and we're left with 637.
Grab the next digit (5) from the dividend, add it to 637, then carry on: 6375 / 816

Going ahead to step 7:
6375 divided by 816 is 7 with a remainder of 663.
Write down 7 as next digit of the result. 
Result so far: 7547.0
Subtract 5712 from 6375 to get 663.
Grab the next digit (9) from the dividend, add it to 663, then carry on: 6639 / 816

Moving on to step 8:
816 goes into 6639 8 times with a remainder of 111.
Use 8 as the next digit of our solution. 
Result so far: 75478.0
Deduct 6528 from 6639 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 9:
816 can be fit into 1110 1 times, resulting in a remainder of 294.
Record the quotient 1 as the next digit in the result. 
Result so far: 75478.1
Subtract 816 from 1110 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 10:
816 goes into 2940 3 times with a remainder of 492.
Write down 3 as next digit of the result. 
Result so far: 75478.13
If we subtract 2448 from 2940, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Going ahead to step 11:
When dividing 4920 by 816, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 75478.136
If we subtract 4896 from 4920, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
816 can be fit into 240 0 times, resulting in a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 75478.136
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 13:
The number 816 fits into 2400 2 times, leaving a remainder of 768.
Use 2 as the next digit of our solution. 
Result so far: 75478.13602
The remainder is 768 after subtracting 1632 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Step 14:
7680 divided by 816 is 9 with a remainder of 336.
Use 9 as the next digit of our solution. 
Result so far: 75478.136029
If we subtract 7344 from 7680, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 15:
The number 816 fits into 3360 4 times, leaving a remainder of 96.
Write down 4 as next digit of the result. 
Result so far: 75478.1360294
Subtract 3264 from 3360 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 16:
The number 816 fits into 960 1 times, leaving a remainder of 144.
The next digit of our result is 1. 
Result so far: 75478.13602941
Deduct 816 from 960 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

In conclusion, the division gives 75478.13602941 with a balance of 1.44e-07.
