78473986 ÷ 978 
Our goal is to divide 78473986 by 978.

Advancing to step 1:
When dividing 7 by 978, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 978

Step 2:
78 divided by 978 is 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Fetch the next digit (4) from the dividend, attach it to 78 and continue: 784 / 978

Advancing to step 3:
The number 978 fits into 784 0 times, leaving a remainder of 784.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 784 after subtracting 0 from 784.
Bring next digit (7) of the dividend behind the 784 and repeat the process: 7847 / 978

Moving on to step 4:
The number 978 fits into 7847 8 times, leaving a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 23 after subtracting 7824 from 7847.
Grab the next digit (3) from the dividend, add it to 23, then carry on: 233 / 978

On to step 5:
978 goes into 233 0 times with a remainder of 233.
Use 0 as the next digit of our solution. 
Result so far: 80.0
The remainder is 233 after subtracting 0 from 233.
Include the next digit (9) from the dividend after 233, then repeat: 2339 / 978

Step 6:
When dividing 2339 by 978, we get 2 with a remainder of 383.
Record the quotient 2 as the next digit in the result. 
Result so far: 802.0
If we take 1956 away from 2339, we end up with 383.
Append the next digit (8) from the dividend to 383 and continue with: 3838 / 978

Advancing to step 7:
The number 978 fits into 3838 3 times, leaving a remainder of 904.
Use 3 as the next digit of our solution. 
Result so far: 8023.0
The remainder is 904 after subtracting 2934 from 3838.
Bring next digit (6) of the dividend behind the 904 and repeat the process: 9046 / 978

Moving on to step 8:
9046 divided by 978 is 9 with a remainder of 244.
Record the quotient 9 as the next digit in the result. 
Result so far: 80239.0
Deduct 8802 from 9046 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 9:
978 can be fit into 2440 2 times, resulting in a remainder of 484.
Use 2 as the next digit of our solution. 
Result so far: 80239.2
Subtract 1956 from 2440 to get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

On to step 10:
978 goes into 4840 4 times with a remainder of 928.
Record the quotient 4 as the next digit in the result. 
Result so far: 80239.24
If we subtract 3912 from 4840, we get 928.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9280, and continue the process.

Moving on to step 11:
When dividing 9280 by 978, we get 9 with a remainder of 478.
Write down 9 as next digit of the result. 
Result so far: 80239.249
Subtracting 8802 from 9280 leaves us with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Step 12:
978 goes into 4780 4 times with a remainder of 868.
Record the quotient 4 as the next digit in the result. 
Result so far: 80239.2494
The remainder is 868 after subtracting 3912 from 4780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8680, and continue the process.

Moving on to step 13:
8680 divided by 978 is 8 with a remainder of 856.
The number 8 becomes the next digit in our result. 
Result so far: 80239.24948
Subtracting 7824 from 8680 leaves us with 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Advancing to step 14:
When dividing 8560 by 978, we get 8 with a remainder of 736.
Put 8 as the next digit of the answer. 
Result so far: 80239.249488
If we take 7824 away from 8560, we end up with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Our division results in 80239.249488 with a remaining 7.36e-05.
