80403194 ÷ 953 
Our goal is to divide 80403194 by 953.

Step 1:
953 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 953

Moving on to step 2:
If we divide 80 by 953, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 953

Let's proceed to step 3:
The number 953 fits into 804 0 times, leaving a remainder of 804.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 804 to get 804.
Grab the next digit (0) from the dividend, add it to 804, then carry on: 8040 / 953

Moving on to step 4:
If we divide 8040 by 953, we get 8 and a remainder of 416.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 7624 from 8040 and we're left with 416.
Include the next digit (3) from the dividend after 416, then repeat: 4163 / 953

Advancing to step 5:
If we divide 4163 by 953, we get 4 and a remainder of 351.
Write down 4 as next digit of the result. 
Result so far: 84.0
Deduct 3812 from 4163 and we're left with 351.
Append the next digit (1) from the dividend to 351 and continue with: 3511 / 953

Advancing to step 6:
If we divide 3511 by 953, we get 3 and a remainder of 652.
Record the quotient 3 as the next digit in the result. 
Result so far: 843.0
The remainder is 652 after subtracting 2859 from 3511.
Fetch the next digit (9) from the dividend, attach it to 652 and continue: 6529 / 953

Step 7:
When dividing 6529 by 953, we get 6 with a remainder of 811.
The number 6 becomes the next digit in our result. 
Result so far: 8436.0
If we subtract 5718 from 6529, we get 811.
Take the next digit (4) from the dividend and append it to 811, then repeat: 8114 / 953

Step 8:
The number 953 fits into 8114 8 times, leaving a remainder of 490.
Use 8 as the next digit of our solution. 
Result so far: 84368.0
If we take 7624 away from 8114, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 9:
The number 953 fits into 4900 5 times, leaving a remainder of 135.
Use 5 as the next digit of our solution. 
Result so far: 84368.5
Deduct 4765 from 4900 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 10:
1350 divided by 953 is 1 with a remainder of 397.
The next digit of our result is 1. 
Result so far: 84368.51
If we take 953 away from 1350, we end up with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Advancing to step 11:
3970 divided by 953 is 4 with a remainder of 158.
The number 4 becomes the next digit in our result. 
Result so far: 84368.514
If we take 3812 away from 3970, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 12:
The number 953 fits into 1580 1 times, leaving a remainder of 627.
Write down 1 as next digit of the result. 
Result so far: 84368.5141
If we subtract 953 from 1580, we get 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

On to step 13:
If we divide 6270 by 953, we get 6 and a remainder of 552.
Write down 6 as next digit of the result. 
Result so far: 84368.51416
Deduct 5718 from 6270 and we're left with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Step 14:
The number 953 fits into 5520 5 times, leaving a remainder of 755.
The number 5 becomes the next digit in our result. 
Result so far: 84368.514165
Subtract 4765 from 5520 to get 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Let's proceed to step 15:
The number 953 fits into 7550 7 times, leaving a remainder of 879.
Record the quotient 7 as the next digit in the result. 
Result so far: 84368.5141657
Subtract 6671 from 7550 to get 879.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8790, and continue the process.

Let's proceed to step 16:
8790 divided by 953 is 9 with a remainder of 213.
Write down 9 as next digit of the result. 
Result so far: 84368.51416579
Subtract 8577 from 8790 to get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

The final outcome is 84368.51416579, with a leftover of 2.13e-07.
