We look at the division of 85807193 by 902 
We want to divide 85807193 by 902.

Let's proceed to step 1:
The number 902 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 902

Advancing to step 2:
902 can be fit into 85 0 times, resulting in a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Fetch the next digit (8) from the dividend, attach it to 85 and continue: 858 / 902

Moving on to step 3:
When dividing 858 by 902, we get 0 with a remainder of 858.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 858, we get 858.
Bring next digit (0) of the dividend behind the 858 and repeat the process: 8580 / 902

Advancing to step 4:
8580 divided by 902 is 9 with a remainder of 462.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 8118 from 8580 and we're left with 462.
Fetch the next digit (7) from the dividend, attach it to 462 and continue: 4627 / 902

Moving on to step 5:
The number 902 fits into 4627 5 times, leaving a remainder of 117.
The next digit of our result is 5. 
Result so far: 95.0
Subtracting 4510 from 4627 leaves us with 117.
Bring next digit (1) of the dividend behind the 117 and repeat the process: 1171 / 902

Moving on to step 6:
If we divide 1171 by 902, we get 1 and a remainder of 269.
Record the quotient 1 as the next digit in the result. 
Result so far: 951.0
If we subtract 902 from 1171, we get 269.
Take the next digit (9) from the dividend and append it to 269, then repeat: 2699 / 902

Step 7:
902 can be fit into 2699 2 times, resulting in a remainder of 895.
The number 2 becomes the next digit in our result. 
Result so far: 9512.0
If we subtract 1804 from 2699, we get 895.
Take the next digit (3) from the dividend and append it to 895, then repeat: 8953 / 902

On to step 8:
When dividing 8953 by 902, we get 9 with a remainder of 835.
The number 9 becomes the next digit in our result. 
Result so far: 95129.0
Subtract 8118 from 8953 to get 835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

Advancing to step 9:
902 goes into 8350 9 times with a remainder of 232.
Write down 9 as next digit of the result. 
Result so far: 95129.9
The remainder is 232 after subtracting 8118 from 8350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 10:
When dividing 2320 by 902, we get 2 with a remainder of 516.
Use 2 as the next digit of our solution. 
Result so far: 95129.92
Subtract 1804 from 2320 to get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Let's proceed to step 11:
902 can be fit into 5160 5 times, resulting in a remainder of 650.
Use 5 as the next digit of our solution. 
Result so far: 95129.925
The remainder is 650 after subtracting 4510 from 5160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Advancing to step 12:
The number 902 fits into 6500 7 times, leaving a remainder of 186.
Write down 7 as next digit of the result. 
Result so far: 95129.9257
If we subtract 6314 from 6500, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 13:
The number 902 fits into 1860 2 times, leaving a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 95129.92572
If we subtract 1804 from 1860, we 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.

Let's proceed to step 14:
560 divided by 902 is 0 with a remainder of 560.
The number 0 becomes the next digit in our result. 
Result so far: 95129.92572
If we subtract 0 from 560, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 15:
The number 902 fits into 5600 6 times, leaving a remainder of 188.
Put 6 as the next digit of the answer. 
Result so far: 95129.9257206
If we take 5412 away from 5600, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 16:
If we divide 1880 by 902, we get 2 and a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 95129.92572062
If we subtract 1804 from 1880, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 95129.92572062, with a leftover of 7.6e-08.
