73086472 divided by 400 
Our goal is to divide 73086472 by 400.

Advancing to step 1:
When dividing 7 by 400, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 400

Going ahead to step 2:
73 divided by 400 is 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Take the next digit (0) from the dividend and append it to 73, then repeat: 730 / 400

Advancing to step 3:
730 divided by 400 is 1 with a remainder of 330.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 330 after subtracting 400 from 730.
Append the next digit (8) from the dividend to 330 and continue with: 3308 / 400

Going ahead to step 4:
400 goes into 3308 8 times with a remainder of 108.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 3200 from 3308 and we're left with 108.
Append the next digit (6) from the dividend to 108 and continue with: 1086 / 400

Going ahead to step 5:
400 goes into 1086 2 times with a remainder of 286.
Put 2 as the next digit of the answer. 
Result so far: 182.0
Subtracting 800 from 1086 leaves us with 286.
Bring next digit (4) of the dividend behind the 286 and repeat the process: 2864 / 400

Step 6:
400 can be fit into 2864 7 times, resulting in a remainder of 64.
Record the quotient 7 as the next digit in the result. 
Result so far: 1827.0
Deduct 2800 from 2864 and we're left with 64.
Grab the next digit (7) from the dividend, add it to 64, then carry on: 647 / 400

Advancing to step 7:
The number 400 fits into 647 1 times, leaving a remainder of 247.
Write down 1 as next digit of the result. 
Result so far: 18271.0
Subtracting 400 from 647 leaves us with 247.
Bring next digit (2) of the dividend behind the 247 and repeat the process: 2472 / 400

Moving on to step 8:
2472 divided by 400 is 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 182716.0
Deduct 2400 from 2472 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 9:
720 divided by 400 is 1 with a remainder of 320.
Put 1 as the next digit of the answer. 
Result so far: 182716.1
Subtracting 400 from 720 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 10:
The number 400 fits into 3200 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 182716.18
Subtracting 3200 from 3200 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
400 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 182716.18
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
400 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 182716.18
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 182716.18, with a leftover of 0.0.
