We look at the division of 8437873 by 359 
We want to divide 8437873 by 359.

Step 1:
When dividing 8 by 359, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 359

Moving on to step 2:
When dividing 84 by 359, we get 0 with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Grab the next digit (3) from the dividend, add it to 84, then carry on: 843 / 359

On to step 3:
359 goes into 843 2 times with a remainder of 125.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 125 after subtracting 718 from 843.
Fetch the next digit (7) from the dividend, attach it to 125 and continue: 1257 / 359

On to step 4:
359 can be fit into 1257 3 times, resulting in a remainder of 180.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtracting 1077 from 1257 leaves us with 180.
Take the next digit (8) from the dividend and append it to 180, then repeat: 1808 / 359

On to step 5:
If we divide 1808 by 359, we get 5 and a remainder of 13.
The next digit of our result is 5. 
Result so far: 235.0
The remainder is 13 after subtracting 1795 from 1808.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 359

Advancing to step 6:
359 can be fit into 137 0 times, resulting in a remainder of 137.
Put 0 as the next digit of the answer. 
Result so far: 2350.0
If we take 0 away from 137, we end up with 137.
Append the next digit (3) from the dividend to 137 and continue with: 1373 / 359

Step 7:
359 can be fit into 1373 3 times, resulting in a remainder of 296.
The number 3 becomes the next digit in our result. 
Result so far: 23503.0
The remainder is 296 after subtracting 1077 from 1373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 8:
359 can be fit into 2960 8 times, resulting in a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 23503.8
If we subtract 2872 from 2960, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 9:
The number 359 fits into 880 2 times, leaving a remainder of 162.
Record the quotient 2 as the next digit in the result. 
Result so far: 23503.82
Deduct 718 from 880 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 10:
When dividing 1620 by 359, we get 4 with a remainder of 184.
Use 4 as the next digit of our solution. 
Result so far: 23503.824
The remainder is 184 after subtracting 1436 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 11:
The number 359 fits into 1840 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 23503.8245
Subtracting 1795 from 1840 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 12:
The number 359 fits into 450 1 times, leaving a remainder of 91.
Put 1 as the next digit of the answer. 
Result so far: 23503.82451
Subtract 359 from 450 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 13:
910 divided by 359 is 2 with a remainder of 192.
Record the quotient 2 as the next digit in the result. 
Result so far: 23503.824512
Deduct 718 from 910 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 14:
1920 divided by 359 is 5 with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 23503.8245125
Subtracting 1795 from 1920 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 15:
If we divide 1250 by 359, we get 3 and a remainder of 173.
Write down 3 as next digit of the result. 
Result so far: 23503.82451253
If we subtract 1077 from 1250, we get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

The final outcome is 23503.82451253, with a leftover of 1.73e-07.
